anyone know codes for arduino bases alcohol sensor mobile app ?

message me [email protected]

Hey I m a computer student and I need a project related to my field but it should include ARDUINO board in it which means it should be 60% hardware and the rest software. Can you please suggest me some of my requirement ? If it is possible please notify me

In the 1950s Popular Electronics published an article for constructing what was then a rudimentary computer game. It consisted of 21 lights with a ‘player’ button and a ‘machine’ button. A player,,could light 1, 2, or 3 lamps, the “machine:” could then also light 1, 2, or 3, lamps, each taking turns. The object of the game was to avoid being forced into lighting the last, or 21st lamp The “machine” would invariably win.. It worked on the principle that within the number 21, there are 5 groups of 4, with 1 left over. The secret was that whichever the “player” chooses (1,,2, or 3), the machine will always chose a number that adds up to 4. ( If the “player” chooses 1,, -the “machine” chooses 3,. If the “player chooses 2,,,the “machine” will choose 2.. If the “player” chooses 3, the , “machine will choose 1) The combination always adds up to 4. The original game used a mechanical ‘stepping’ relay and ordinary pilot lamps. I am looking for someone to take this on as a project using LEDs and processors. (Arduino maybe?) Will be glad to answer any questions.

Want To Learn Arduino? Get Building With These Arduino Projects!

In this article, I cover the 30 best Arduino projects you need to build in 2024, including a range of cool Arduino project ideas for beginners and more advanced users.

One of the best ways to learn all about Arduino is to get hands-on with project-based learning.

But what can you do with Arduino projects in 2024? Honestly, I think the possibilities are nearly limitless! It all comes down to imagination!

Whether you’re intrigued by automation systems, robotics, or interactive art installations, Arduino projects enable all this and much, much more.

They’re also an excellent way to hone your electronics skills if you’re actively looking for jobs in IoT .

So, if you’re driven by a desire to innovate, have a passion for technology, or enjoy creating, let’s dive into some fun Arduino projects!

• What Is Arduino?

If you’re new to Arduino, you’re probably wondering, what exactly is Arduino?

Great question! Let me cover the basics before we dive into some easy Arduino projects!

Arduino is an open-source electronics platform consisting of easy-to-use hardware and software.

You'll often hear about Arduino and Raspberry Pi when it comes to microelectronics in 2024, but that's a discussion for another day.

An Arduino board is a programmable microcontroller that includes various inputs and outputs (I/O), like serial communication, digital inputs and outputs, and analog inputs.

This is very cool indeed and a far cry from the basic breadboards I used to learn about electronics during my undergraduate studies.

Arduino boards are typically used in a free and open-source development environment. Combining these allows you to write, upload, and execute code that controls your device, invention, or project.

One of the coolest ways to use Arduino is to get creative, whether you want to build a simple LED light device or are interested in IoT (Internet of Things) or robotics.

And if you’re just starting out, there’s a huge and active Arduino community that offers support, shares their own projects, and more. 

Of course, if you’re brand new to the world of Arduino and you’re not sure where to start, we’d definitely recommend complementing your projects with an Arduino course.

• What Skills Do You Need For Arduino Projects?

Let's set the record straight: you don’t need to be an expert to start working on Arduino projects! In fact, I genuinely think that Arduino projects can be great for all skill levels.

That said, you should probably have some basic skills before you get started, or at least be willing to learn them!

For example, Arduino projects usually involve C++ coding if you're building from scratch, so consider a C++ course if this sounds like fun, but you're not familiar with the language.

Let's take a look at the basics I think you should have to follow along with our Arduino projects:

• Basic programming knowledge: Even if you’re following along with someone else’s code, basic programming knowledge is useful for figuring out any issues that may come up.
• C or C++ skills: Arduino is based on C++, so it's really helpful to have C++ skills to create your own projects from scratch.
• Basic electronics knowledge: Arduino projects involve working with various electrical components, so it’s essential to understand the basics of current, voltage, and resistance.
• Ability to read schematics: Arduino projects often come with schematics that make them easy to replicate, so you’ll need to be able to read these to work with these kits or projects.

I should point out that it’s also really easy for complete beginners to pick up easy Arduino projects and learn these skills along the way.

But if you are feeling uncertain, I also think it helps to pick up an Arduino book for some extra help if you're brand new to the area.

I know from experience that it's always nice to have some reference materials on hand!

• Best Arduino Projects for Beginners in 2024

To get things started, I'll start with ten Arduino starter projects that are generally on the simpler side.

This means they require less time to put together, and they're also a great way to get a taste of what you can do with Arduino!

1. PC Info Panels

Download Source Code

Why We Chose This Project

First up on our list is one of the best beginner Arduino projects for newbies. I really like this as a gentle introduction, as you’ll use an Arduino Nano to interface between an LCD display and your computer’s USB port.

Once the electrical components are assembled, you can use open-source software called LCD Smartie to show different kinds of information on your LCD screen, including system stats like network utilization, CPU load, disk space, and more.

I also like that you can use your info panel to download RSS feeds or run other applications. Very cool!

2. Vintage Screensaver

This might be appealing to me because of the nostalgia, but if you're new to Arduino, simple projects like this vintage screensaver are a great way to start!

Inspired by 90s screensavers, you can get a healthy dose of 90s retro styling with the TVOUT and a Yourduino.

I also like that there are nine screensavers to choose from, making it a fun way to create an interesting decorative piece and even reuse an old CRT display.

Although you might need to dig around for a CRT display, as they're not very common anymore!

3. ArduSniffer

I really like this one, as it's a genuinely useful project! With the ArduSniffer, you can create a USB-powered gas detector with an LED display.

Sure, it does have more components than the first two projects on our list, but I want to gradually introduce you to more challenging projects as we work down the list.

That said, I think this is a great way to level up your skills. Plus, it's pretty affordable and offers detailed instructions.

4. Bluetooth Controlled RC Car

If you like remote-controlled cars (we’ve all had one at some point, right?!), you'll love this project, as it uses Bluetooth, an app on your phone, and an Arduino. 

I like that the instructions are pretty basic, as it makes it easy for you to put the car together and make it work.

But if you want to get creative, you can use a 3D printer (or printing service) to design a body for the car!

5. Stroboscope (Zoetrope)

A zoetrope , sometimes called a stroboscope, is a pre-film mechanical device that gives the illusion of animation or motion. I love this project, and it's great if you’re a cinema fan! 

To build this Arduino project, you can reuse a defunct Xbox 360 CD drive with a spindle motor to recreate this cool gadget.

You get all the instructions and source code you need in the instructable, making this a great way to create a short animation (or the illusion of one).

6. Portable Temp/Humidity Sensor with an LCD Display

I think this portable temperature and humidity sensor is a fun beginner Arduino project, as it's easy to understand really relatable.

This particular project uses an Arduino UNO R3, but you can use any 5V Arduino board you choose, and you can even purchase new parts or salvage some from your old projects.

The code, which was made using the Adafruit DHT library, is included in the instructions, and you can power your sensor using a power bank to display data in real time.

7. Simple Programmable Robotic Arm

Do you like robots? If the answer is yes, read on!

This is one of the best Arduino robot projects for beginners, as you'll create a simple and programmable servo arm using Arduino UNO and the Arduino IDE.

The robot arm itself uses buttons and potentiometers to record and play five programmed positions. 

I like that this can be powered by your computer’s USB port, but you can also use an external power supply if you ensure the servo can handle it.

It's easy to make the bot arm from readily available materials, and the code and circuit schematics are included.

8. Nano Piano

Do you fancy yourself as Beethoven or Bach? Just kidding, but if you like music, this is a cool Arduino project.

It is a beginner-friendly project with all the schematics and code you need to build a miniature piano with four keys using the Arduino Nano Every.

I also like that you can tailor the Nano Piano to your style by choosing your base (perf or protoboard) and deciding whether you want to create a housing with 3D printing!

9. Coin Sorter

Do you have pockets full of change you don't know what to do with? Maybe, maybe not! I mean, who uses real money anymore, right?!

That said, if you’ve ever wanted to sort your coins, this simple Arduino project might be one to try.

All you need is an Arduino UNO, a 16x2 display, and an infrared (IR) sensor to detect the differences between each coin, sending them through the appropriate hole.

I need to point out that it’s super important to follow the instructions as accurately as possible. This includes marking and cutting the sorting holes precisely and ensuring the slopes are appropriately angled.

You can even create a simple prototype from cardboard or 3D print a body for the sorter.

10. Blind Spot Monitoring System

Rounding out our list of projects for beginners, this is a really interesting Arduino project if you're intrigued by real-world microelectronics applications.

In fact, this project even takes its inspiration from the 2021 Mercedes Benz S-Class, which used ambient lighting to blink when a vehicle is detected in the blind spot. We've probably all seen these features in modern cars now, but it was revolutionary at the time.

In this case, we’ll be using an Arduino Uno and an RGB LED light strip to mimic the same thing. You can also set it to blink different colors depending on the position of the other vehicle relative to yours.

While there are many Arduino LED Projects to choose from, I really like this one as it's incredibly beginner-friendly and relatable.

• Cool Arduino Projects for Intermediate Users

Do you feel ready to take it to the next level? Let’s take a look at some intermediate-level projects!

11. Emotive Plant Pot

Ready for some more fun Arduino project ideas? Great, how do you feel about making an Emotive Plant Pot?

Now, let me take a second to say that this is not going to be Groot from Guardians of the Galaxy (I know!), but it's actually a 3D-printed plant pot with an LCD display that you can use to show cute faces.

You can even 3D print the components yourself with the included files. Just use the detailed instructions and schematics, and away you go!

12. Touch Interface Controlled Robotic Arm

We're back to robotics! If this is something you like, definitely check out this touch interface robotic arm.

All you need is an Arduino and any older Android phone to get started. I think this is also a cool way to get more mileage from older tech! 

Now, as you'd expect, this project is a little more complex, but the schematics and code are provided, and there’s even an assembly guide with a clear video to demonstrate the steps.

You can also 3D print the components yourself or use a 3D printing service with the provided files.

Note that creator Maurizio Miscio states you can contact him for the graphical interface app’s code.

13. Hidden Smart Bookshelf

This one just sounds cool, so I had to include it! The idea here is to create a Hidden Smart Home Bookshelf that you can use to conceal items within a cabinet or shelf that’s meant to look like a full bookshelf.

The creator has even included a very detailed video to cover the building and assembly process.

If you want to access the Arduino source code, head over to the creator’s GitHub , and you can either follow along exactly or make your own improvements.

I also think that if you have extra space, you could scale this up into a concealed closet or door!

14. Neopixel Cake

I think this is one of those super cool Arduino project ideas that you can use to make a splash at a party or special event.

Yep, you can make a uniquely memorable cake that uses flexible LED matrices and an Arduino.

The matrices themselves are embedded into the cake, then covered with fondant icing to allow light diffusion and a much better effect. Watch out Cake Boss!

I also found that you can even program cool light effects or text into the LED matrix so it can display whatever you want.

Just follow the detailed video demo and make sure you have a cake ready!

15. Automatic Humidifier

If you live somewhere hot and dry, you probably know all too well how important it is to have a humidifier.

Well, you can build your own now! I love this project to create an automatic humidifier, and it's straight from the Arduino Project Hub.

This project revolves around using a DHT11 temperature and humidity sensor to detect environmental humidity, and this can trigger the humidifier whenever the detected humidity is below a set level.

16. CNC Drawing Machine

This is another flashback for me to my undergraduate studies and the class I took in electronics and manufacturing.

The idea here with this Arduino project is to create a CNC (Computer Numerical Control) plotter out of an Arduino Nano board and two old DVD writers.

This is definitely another slightly old-school project, but I love the way it can be used to create 2D or 3D images on plain or smooth surfaces with an Arduino and a printing mechanism. 

17. 32-Band Audio Spectrum Visualizer Analyzer

This is another project for music lovers, as it's a cool Arduino project to create a 32-band audio or music frequency visualizer (also called an analyzer).

I found that this audio visualizer mixes signals from the left and right channels to ensure no beats are missed, and it also has five display modes that you can switch with the push of a button.

It's also cool that the audio feed can be taken from a line out or the headphone port of an amplifier or sound system!

18. Mind Control Drone

Now we’re not promising that this project will make you into the next Charles Xavier, but with a Mindwave Neurosky sensor and an Arduino, you can have a slice of this futuristic idea by building a mind control drone.

Let me make it super clear! This project doesn’t allow you to fly a drone with your mind, per se.

But you can control the drone’s liftoff and landing with your mind, which is pretty cool!

I think this is an awesome project for learning how to hack a PCB and control it digitally.

It’s also worth mentioning that the creator warns that you may mess up your drone and its controller when building this project, so be careful !

19. IoT Pet Feeder

If you’re looking for Arduino IoT Projects, this is a great choice, as you can build a smart food dispenser that can be controlled from your phone. 

I like these kinds of projects, as they're practical and great for enthusiasts who also want to pursue a career in electronics.

All you'll need to create it is an Arduino UNO, a servo, a PIR motion sensor, and a small speaker.

You can even adapt this project and turn it into an automatic bird or squirrel feeder for your backyard!

Feel free to set your smart pet feeder up any way you’d like, but the default instructions are designed to set the feeder to beep at a set interval. Then, when your pet investigates the sound, a PIR motion sensor triggers the servo to dispense food. 

If you’re a fan of Back to the Future, think of this as your own way to feed your very own Einstein!

20. Smart Dustbin

Rounding out our intermediate project list, this is a full project kit that you can use to create a hands-free, self-operating dustbin that's controlled with claps or foot taps. 

This is pretty cool and a great way to add some electronic magic to your ordinary household items. You’ll just need an audio sensor to detect your claps or taps.

The dustbin can also send IoT notifications to let users know when the bin is full, thanks to an ultrasonic sensor that detects garbage levels. 

• The Best Arduino Projects for Advanced Users

If you feel like your Arduino skills are at the expert level, or if you’re feeling adventurous, these advanced projects might be the right ones for you. Let’s take a look!

21. Star Tracker (Low Cost)

If you like looking into space, this is a great Arduino project, as it uses an equatorial mount to take pictures of the sky at night.

If you’re not 100% sure what that means, no problem!

An equatorial mount is a telescope mount that allows telescopes or cameras to follow the earth’s rotation, ensuring any long exposures come out clearly. 

I also found that this project creator claimed the Star Tracker is easier than putting together Ikea furniture and just about as affordable. What an endorsement!

Despite being an advanced project, the Star Tracker is relatively user-friendly, with all the requirements listed in the GitHub repo.

Be sure to share your photos with us after you build this project!

22. The Gaggiuino Coffee Machine

Do you like coffee? I have a strong suspicion that the answer is yes!

In that case, this is one of the best Arduino projects for you! But you don’t need to be an engineering student to give it an espresso shot (get it?). 

This project uses an Arduino or an STM32 Blackpill to create a “smart coffee” experience, where the end product is an aftermarket mod of many coffeemakers.

There’s even an active community around this mod, which you can find on their Discord server , along with videos from project users.

23. Automated Bean Sprouter

If you like the idea of self-sustainability and growing your own foods, you might be intrigued by this project! What's more, if you love bean sprouts, you have to try it!

The idea here is to build your own automated bean sprouter by using stacked trays, a rotating motor, and a watering system to keep your sprouts hydrated while helping air circulate and keep mold growth at bay. 

This is another super practical project that you can actually use in your daily life, which I really like.

The project page includes all the necessary information, including the component list, schematics, and code.

As an advanced project, it’s not the easiest, but you’ll never need to buy sprouts again!

24. UV Meter and Breathalyzer Keychain

This is a really interesting Arduino project that uses a UV sensor to create your own alcohol breathalyzer in the form of a keychain.

All you need to create this handy keychain is an Arduino Pro Mini 328 and an Arduino UNO (or FTDI). The keychain itself is powered by three 200mAh Li-ion batteries that you can recharge via the USB charging port.

To finish things off, you will use an OLED screen to display everything you need.

Detailed instructions are provided with this project, including 3D files so you can print the spherical casing yourself (or get it printed by a 3D printing service). 

25. Path Memorizing Robot

I like this project, as it's a classic for electronics students and anyone interested in self-driving cars.

You'll just need to use an Arduino Uno to control a little robotic car designed to navigate through a predefined path before returning to its starting point.

Before you create this path-memorizing robot, you’ll need to build a regular remote-controlled car using an IR receiver and remote.

But this is super easy if you follow the instructions and use all the provided code and schematics.

26. Arduino 3D Wire Bending Machine

I think this is a cool project if you like to be creative with industrial materials.

The idea here is to create an Arduino-based wire-bending machine that you can use to bend wires into all sorts of 3D designs.

You'll use an Arduino to control the motor and wire feeder movements, while a 3D-printed jig allows the machine to bend the wire into your desired shapes.

I also like that you can bend wire of varying shapes and diameters and adjust the radius and bending angle. 

This project itself involves mechanical, electrical, and computer engineering all in one, making it a fantastic choice for engineering students or professionals.

27. Camera Slider

Here, we have another cool Arduino project for photography enthusiasts.

In fact, if you've ever wanted to create cinematic shots with your camera, you might have considered a camera slider. Well, this is the project for you!

The plan here is to create a motorized slider for your camera that will allow you to achieve smooth movements and get cinematic shots.

You’ll need aluminum, a timing belt, and stepper motors, along with an Arduino to move the camera. You also need a rotary encoder that allows you to move the slider back and forth.

You can use practically any camera you want in this rig, as long as it can attach to the DSLR mount!

28. Self-Parking Car with Ultrasonic Sensor

Maybe you fancy yourself as the next competitor to Elon Musk’s Tesla?

Or maybe you just think self-parking cars sound cool?

Either way, I think this is a really fun build that allows you to create an advanced self-parking car via path-finding algorithms.

All you need to dois order the full kit, and you’ll be ready to get building!

29. LED Cube

We're getting close to the end of our list, and I thought it would be fun to include something cool to look at!

With this LED Cube project, you can build a complex LED cube with 512 LED lights, and this can be programmed to show cool lighting patterns and all sorts of effects.

I also really appreciate that the creator documents the building process in a YouTube video, making it easy for you to follow along. 

Schematics and code are all provided, so all you need to do is gather the components, and you’re ready to build!

30. Magnet Plant Levitation System

Here we are, the final Arduino project on my list!

And what a way to wrap things up, but with a super cool Arduino project that suspends a plant in mid-air by using the power of electromagnetic fields.

It honestly feels like science fiction, but nope, this really works! Just follow the tutorial, as it offers a detailed guide, including the STL files for the 3D-printed components.

I know the list of components required for this project is long, but I really think the end result is totally worth it to build a plant levitator!

• Wrapping Up

17 Cool Arduino Project Ideas for DIY Enthusiasts

Arduino is an open-source electronics platform that combines both open source software and hardware to let people make interactive projects with ease. You can get Arduino-compatible single board computers and use them to make something useful.

In addition to the hardware, you will also need to know the Arduino language to use the Arduino IDE to successfully create something.

You can code using the web editor or use the Arduino IDE offline. Nevertheless, you can always refer to the official resources available to learn about Arduino.

Considering that you know the essentials, I will be mentioning some of the best (or interesting) Arduino projects. You can try to make them for yourself or modify them to come up with something of your own.

Interesting Arduino project ideas for beginners, experts, everyone

The following projects need a variety of additional hardware – so make sure to check out the official link to the projects ( originally featured on the official Arduino Project Hub ) to learn more about them.

Also, it is worth noting that they aren’t particularly in any ranking order – so feel free to try what sounds best to you.

1. LED Controller

Looking for simple Arduino projects? Here’s one for you.

One of the easiest projects that let you control LED lights. Yes, you do not have to opt for expensive LED products just to decorate your room (or for any other use-case), you can simply make an LED controller and customize it to use it however you want.

It requires using the Arduino UNO board and a couple more things (which also includes an Android phone). You can learn more about it in the link to the project below.

2. Hot Glue LED Matrix Lamp

Another Arduino LED project for you. Since we are talking about using LEDs to decorate, you can also make an LED lamp that looks beautiful.

For this, you might want to make sure that you have a 3D printer. Next, you need an LED strip and Arduino Nano R3 as the primary materials.

Once you’ve printed the case and assembled the lamp section, all you need to do is to add the glue sticks and figure out the wiring. It does sound very simple to mention – you can learn more about it on the official Arduino project feature site.

3. Arduino Mega Chess

Want to have a personal digital chessboard? Why not?

You’ll need a TFT LCD touch screen display and an Arduino Mega 2560 board as the primary materials. If you have a 3D printer, you can create a pretty case for it and make changes accordingly.

Take a look at the original project for inspiration.

4. Enough Already: Mute My TV

A very interesting project. I wouldn’t argue the usefulness of it – but if you’re annoyed by certain celebrities (or personalities) on TV, you can simply mute their voice whenever they’re about to speak something on TV.

Technically, it was tested with the old tech back then (when you didn’t really stream anything). You can watch the video above to get an idea and try to recreate it or simply head to the link to read more about it.

5. Robot Arm with Controller

If you want to do something with the help of your robot and still have manual control over it, the robot arm with a controller is one of the most useful Arduino projects. It uses the Arduino UNO board if you’re wondering.

You will have a robot arm -for which you can make a case using the 3D printer to enhance its usage and you can use it for a variety of use-cases. For instance, to clean the carbage using the robot arm or anything similar where you don’t want to directly intervene.

6. Make Musical Instrument Using Arduino

I’ve seen a variety of musical instruments made using Arduino. You can explore the Internet if you want something different than this.

You would need a Pi supply flick charge and an Arduino UNO to make it happen. It is indeed a cool Arduino project where you get to simply tap and your hand waves will be converted to music. Also, it isn’t tough to make this – so you should have a lot of fun making this.

7. Pet Trainer: The MuttMentor

An Arduino-based device that assists you to help train your pet – sounds exciting!

For this, they’re using the Arduino Nano 33 BLE Sense while utilizing TensorFlow to train a small neural network for all the common actions that your pet does. Accordingly, the buzzer will offer a reinforcing notification when your pet obeys your command.

This can have wide applications when tweaked as per your requirements. Check out the details below.

8. Basic Earthquake Detector

Normally, you depend on the government officials to announce/inform about the earthquake stats (or the warning for it).

But with Arduino boards, you can simply build a basic earthquake detector and have transparent results for yourself without depending on the authorities. Click on the button below to know about the relevant details to help make it.

9. Security Access Using RFID Reader

As the project describes – “ RFID tagging is an ID system that uses small radio frequency identification “.

So, in this project, you will be making an RFID reader using Arduino while pairing it with an Adafruit NFC card for security access. Check out the full details using the button below and let me know how it works for you.

10. Smoke Detection using MQ-2 Gas Sensor

This could be potentially one of the best Arduino projects out there. You don’t need to spend a lot of money to equip smoke detectors for your home, you can manage with a DIY solution to some extent.

Of course, unless you want a complex failsafe set up along with your smoke detector, a basic inexpensive solution should do the trick. In either case, you can also find other applications for the smoke detector.

11. Arduino Based Amazon Echo using 1Sheeld

In case you didn’t know 1Sheeld basically replaces the need for an add-on Arduino board. You just need a smartphone and add Arduino shields to it so that you can do a lot of things with it.

Using 5 such shields, the original creator of this project made himself a DIY Amazon Echo. You can find all the relevant details, schematics, and code to make it happen.

12. Audio Spectrum Visualizer

Just want to make something cool? Well, here’s an idea for an audio spectrum visualizer.

For this, you will need an Arduino Nano R3 and an LED display as primary materials to get started with. You can tweak the display as required. You can connect it with your headphone output or simply a line-out amplifier.

Easily one of the cheapest Arduino projects that you can try for fun.

13. Motion Following Motorized Camera

Up for a challenge? If you are – this will be one of the coolest Arduino Projects in our list.

Basically, this is meant to replace your home security camera which is limited to an angle of video recording. You can turn the same camera into a motorized camera that follows the motion.

So, whenever it detects a movement, it will change its angle to try to follow the object. You can read more about it to find out how to make it.

14. Water Quality Monitoring System

If you’re concerned about your health in connection to the water you drink, you can try making this.

It requires an Arduino UNO and the water quality sensors as the primary materials. To be honest, a useful Arduino project to go for. You can find everything you need to make this in the link below.

15. Punch Activated Arm Flamethrower

I would be very cautious about this – but seriously, one of the best (and coolest) Arduino projects I’ve ever come across.

Of course, this counts as a fun project to try out to see what bigger projects you can pull off using Arduino and here it is. In the project, he originally used the SparkFun Arduino Pro Mini 328 along with an accelerometer as the primary materials.

16. Polar Drawing Machine

This isn’t any ordinary plotter machine that you might’ve seen people creating using Arduino boards.

With this, you can draw some cool vector graphics images or bitmap. It might sound like bit of overkill but then it could also be fun to do something like this.

This could be a tricky project, so you can refer to the details on the link to go through it thoroughly.

17. Home Automation

Technically, this is just a broad project idea because you can utilize the Arduino board to automate almost anything you want at your home.

Just like I mentioned, you can go for a security access device, maybe create something that automatically waters the plants or simply make an alarm system.

Countless possibilities of what you can do to automate things at your home. For reference, I’ve linked to an interesting home automation project below.

Bonus: Robot Cat (OpenCat)

A programmable robotic cat for AI-enhanced services and STEM education. In this project, both Arduino and Raspberry Pi boards have been utilized.

You can also look at the Raspberry Pi alternatives if you want. This project needs a lot of work, so you would want to invest a good amount of time to make it work.

Wrapping Up

With the help of Arduino boards (coupled with other sensors and materials), you can do a lot of projects with ease. Some of the projects that I’ve listed above are suitable for beginners and some are not. Feel free to take your time to analyze what you need and the cost of the project before proceeding.

Did I miss listing an interesting Arduino project that deserves the mention here? Let me know your thoughts in the comments.

Introducing the Arduino UNO Mini Limited Edition: Pre-orders now open

One board to rule them all: History of the Arduino UNO

Our 12 favorite Arduino UNO projects

The UNO wasn’t Arduino’s first board, and it won’t be its last . There have been many varieties of microcontroller and maker boards before and after the UNO, but none have been as iconic. As we cross the epic milestone of 10 million UNOs sold and the launch of the UNO Mini Limited Edition , we decided it was time to take a look back at some of our favorite UNO projects from the last 10 years.

And we want to hear about yours, too. Join us over on social media to share your favorite UNO projects, whether you built them yourself or marveled at someone else’s electronic creation.

The Toothbrush Machine

The queen of terrible tech Simone Giertz casually blew the internet’s mind back in 2015 with her robotic skateboard helmet with an automated toothbrush mounted on the front.

Arduino GRANDE

Spend more than five minutes Googling “Arduino UNO” and you’re bound to find yourself looking at the Arduino GRANDE . A fully operational UNO that’s six time bigger than it should be.

Coffee Printer

If you’ve ever left a coffee ring on your notepad or table top, you’ll appreciate how effective it is at leaving a mark. This UNO project put that annoying side effect of coffee to artistic use .

Autonomous “Follow Me” Cooler

Why carry your own beer and sandwiches around like a sucker, when you can “simply” connect a robotic cooler to your smartphone’s Bluetooth®, hook it up with GPS and let if follow you around .

Skeleton Arduino Uno

This Arduino UNO is its own project, which is so meta it’s impossible not to love it ! It’s a PCB without the PCB, and takes “open” source more literally than any other maker board has ever achieved.

Gaming Microwave

Microwave’s used to be considered the fastest way to cook things. But in today’s CPA-addled world, even one-minute noodles take too long. Problem solved ; game while you’re waiting.

This UNO project takes the concept of “everything is a drum” to new levels by turning devices like hard drives, floppy drives, scanners and more into a techno-orchestra .

The Best Arduino Projects – Robots, Sensors, RC, CNC and more

Welcome to my collection of Arduino projects . As a maker, techie and mechatronics engineer I’ve been using Arduino for more then 8 years. Arduino is an incredibly versatile microcontroller with limitless possibilities for developing electronics applications and prototypes.

We can use Arduino for simple tasks such as controlling LEDs and DC motors, to controlling real CNC machines and robots. That’s right, in the following list I will share my Arduino experience with you. You will find Arduino projects for beginners and more advanced projects for Arduino enthusiast.

Even if you are just getting started with Arduino, you don’t have to worry about that. Each of the following DIY Arduino projects is covered with detailed step by step tutorial on how to do it yourself and includes circuit schematics, source codes and videos.

Using the comments section below, you can also suggest your ideas, as well as discuss anything related to these Arduino projects. I will continuously update this article with all new stuff that I make. Last update: February 2022. 

Robotic Arduino Projects

Arduino robot arm.

When it comes to automated manufacturing, robot arms play big role with so many applications. They are often used for welding, assembling, packing, painting, pick and place tasks and much more. This Arduino project is actually a robotic arm made out of 3D printed parts, servo motors joints and controlled using an Arduino Nano. What’s even cooler we can control the robot arm wirelessly via a smartphone and a custom build Android application.

The robot arm has 5 degrees of freedom, so we need 5 servo motors, plus an additional servo for the gripper mechanism. For the communication with the smartphone we use the HC-05 Bluetooth module.

Mecanum Wheels Robot

The following project is one of the coolest Arduino project in this list. It’s an Arduino robot car which instead of normal wheels, it employs omnidirectional wheels or mecanum wheels which enable to robot to move in any direction.

The wheels are attached on four stepper motors which are individually control. By rotating the wheels in certain pattern, they exert diagonal forces due the diagonally positioned rollers on the circumference of the wheels, and so they can move in any direction. The robot car can be remotely controlled either vie Bluetooth communication and an custom build Android application. Also, we can control it using an DIY RC transmitter with the help of the NRF24L01 transceiver module.

Arduino Robot Arm and Mecanum Wheels Platform Automatic Operation

Here’s an upgraded version of the previous mecanum wheels robot project. On top of the platform I added the DIY Arduino Robot Arm project mentioned above and now they can work together.

As the robot uses stepper motors for the wheels and servo motors for the robot arm, we can precisely control them using the custom build Android application. What’s even cooler, we can record the movements of the robot and then the robot can automatically repeat them.

Link: Arduino Robot Arm and Mecanum Wheels Platform Automatic Operation

SCARA Robot – 3D Printed

This Arduino based SCARA robot is a step-up big compared to the previous projects in every aspect. It has a better and more robust design with precisely controlled stepper motors and custom build GUI for controlling it.

As a controller it has an Arduino UNO board, combined with a CNC shield and four A4988 stepper drivers. It has 4 DOF, driven by four NEMA 17 stepper motors.

Laser Engraving Robot

For controlling the robot we are using an Arduino Mega board in combination with a RAMPs board. This a popular combination used for 3D printing and it can be used for laser engraving machines as well. As for a firmware, we are using the Marlin 3D Printer firmware and the Repetier control software .

DIY Mars Perseverance Rover Replica

The rover features a rocker-bogie suspension which allows the rover to run smoothly on uneven terrain, just like the real rover. It has six independently controlled DC motors for driving and four servos for steering, and it’s controlled using an Arduino MEGA board. There’s also an FPV camera located in the cameras unit of the rover which can by used for controlling the rover remotely. The remote control is done with the help of a cheap commercial RC transmitter and receiver.

Arduino Hexapod Robot

I also designed a custom PCB which acts as an Arduino Mega Shield so we can easily attach all servo connects. We can control the ant robot via Bluetooth and a smartphone, or radio communication. The ant also has built-in ultrasonic sensor in the head. With that it can detect objects in front, and it can even strike if the object is present if front of it.

CNC Machines Arduino Projects

Diy laser engraving cnc machine.

The CNC machine is composed of just two linear rails which are secured to a base frame made of 8mm MDF board. For controlling it we are using an Arduino UNO board in combination with a CNC shield and two DRV8825 stepper drivers. As a tool it has an laser module attached so this machine is actually a CNC laser engraver.

The following Arduino project is a great example of utilizing the DIY RC transmitter from above. It’s a 3D printed hovercraft which I entirely designed on my own, and of course, the 3D printing files are available for downloading. The hovercraft uses two brushless motors , one for creating an air cushion for the lift, and the other for generating thrust or moving forward.

Arduino RC Airplane

The airplane is entirely made out of Styrofoam and what’s cooler, the shapes are made with the help of my DIY Arduino CNC Foam Cutting Machine , a project already mention above. The radio communication is based on the NRF24L01 transceiver modules. For that purpose, I used my DIY Arduino RC Transmitter and DIY Arduino RC Receiver .

DIY Air Quality Monitor

In this Arduino project we are building an Air Quality Monitor which can measure several important air quality parameters such as PM2.5, CO2, VOC, Ozone, as well as temperature and humidity. I designed a custom PCB on which we can easily attach the sensors we need and show the results on a 2.8 inches touch display. The device can also keep track of the sensors values from the last 24 hours.

Arduino Projects Ideas

The following section of this article contains Arduino projects ideas based on my detailed tutorials on various sensors and modules, as well as your suggestions from the comments section below.

6-Axis Arduino Robot Arm with Cycloidal or Harmonic Drives as Joints

Harmonic Drive working principle:

We can use NEMA 17 or 23 stepper motors in combination with these drivers which provide high speed reduction ratios. As for controller we could use an Arduino Uno or Arduino MEGA board.

Android Smartphone Controlled Power Outlet Using Arduino

Using your smartphone you can connect and control your power outlet via Bluetooth. You can either use some already made apps for controlling Arduino from the Play Store or create your own custom made app . In this way we can also control the power outlets through voice control commands.

Home Automation Arduino Projects

Of course, there are endless possibilities and combinations for building a home automation system using the Arduino board. You can always change and add more devices. You can also make a Bluetooth communication so you can control all of this using your smartphone etc.

Arduino Gesture Control

44 thoughts on “the best arduino projects – robots, sensors, rc, cnc and more”.

I have not found a more comprehensive site for learning how to use an Arduino and make things with them as the brain. I also like that you can “understand what words are coming out of your mouth”(Chris Tucker and Jackie Chan reference). It makes things much simpler for me. I have a hard time understanding what many YouTubers are saying. I want to become a master of the Arduino quickly. I don’t have time to waste on sites with bits and pieces of information and many times with flat-out wrong information.

I am working on a project similar to your Home Automation using Arduino concept but using the HC-12 because the distance between remote units can be 600′ through trees etc. Basically its a property monitoring system rather than a home based system. Driveway monitor, human presence detection, temp in buildings etc. Your site and videos have given me the inspiration and confidence to give it a go. Thanks for the great content 🙂

Nice to hear it, have fun building! 😀

Hi, I am wondering if anyone has made an outdoor batttery powered wind chime “wobbler” to randomly make the chimes chime on windless days. I imaging a motor with a pulley and a sting attached to the paddle of the wind chime to simulate wind. Our neighbour has a really loud air conditioner and is now adding a pool pump. We would love to not listen to these sitting on our patio. I am an older person with no electrical or mechanical experience but am willing to try to learn.

Hello…I’d like to build an animatronic robot, (although it will closely resemble a talking/singing teddy bear). I need to build a control system that allows me to articulate the bear via custom joystick controllers. The signals will operate 12v relay banks which will engage air valves which in turn will operate pneumatic cylinders. Disneyland style, only on a much smaller scale. But I also need to be able to record the signal information in real time, and be able to make multiple passes during recording. (Example: record head tilt, ear wiggle, and eye movement on first pass…start at the begin again. Now as it plays back the movements I just did, I start operating mouth movement, arm and body movements. These would be recorded on another track. When played back…I have a bouncing talking and singing bear that operates on its on auto-pilot. Can Arduino products help me in any of the challenges that lay ahead for me? Thank you for any info. or thoughts you might have. 🛀Dave.

Hey, sure, you could definitely use an Arduino board as a controller. Depending on of the number of inputs and outputs you could use an Arduino UNO, NANO or MEGA. I’m not sure how much knowledge you have in this field, so I would suggest to check some of my tutorials. I have examples for controlling motors and sensors using custom design joystick controllers, so you might find those helpful. The project would have a lot of work, obviously, but I believe it would be quite interesting. Cheers and so have fun building one!

Thanks! Sure, you could use mostly any board, bought from anywhere, which is Arduino based or compatible for any of these Arduino projects.

Make a dtmf car or drone

Firts of all let me thank you for all effort and very good explanation you put in your projects and videos, you already built a radio controller. Is there any future project to build an arduino based drone and control it throughyou RC controller? I guess ot would be very nice. Thanks again and congratulation for your good work.

Hey, thanks! Well yeah, I will build an Arduino based drone in some of my future videos, but I’m not sure exactly when I will do that. So stay tuned!

I’ve learned a lot from your website especially on how to control a device using a smartphone via bluetooth. Thanks man! You did a great job!

I’m glad to hear this, thanks!

Just want to say, great site, keep up the good work!

Hi Dejan, very nice work you doing here! Are you considering to build some battery project with as low power consumption as possible? Weather station would be a great example but you already built that. Maybe ver. 2.0? 😀

Thank you! Yeah, that’s a good suggestion and I definitely will make projects like that in future. A solar panels for charging can also be implemented.

Thank you. 🙂

Hey, thanks! Yeah, a CNC machine is already on my TO-DO list and I will definitely make one in future. 🙂

Excellent content and information…

Can you please tell me about the 5 volts external power supply(& how to build an another one for Arduino projects) you’ve used in your arduino projects for powering other actuators & devices

I would recommend to get a DC-DC Buck Converter which can be usually set to voltages from 3 to 35 volts, with inputs from 3 to 35 volts. And depending on your application you need to make sure that your buck converter have enough power, or it can handle the amount of current your project needs. Or of course, you can get a particular voltage DC adapter or power supply.

I would like to ask if you could do a tutorial on how to send strings from an android and print it on the computer via bluetooth module and using arduino.

Well check my Arduino Bluetooth tutorial. There I’ve explained how you can make communication between Android and Bluetooth module, as well as Arduino and PC.

How can I build a small cheap fall detection device that sends an alert to a phone when the wearer falls?

You could try to achieve that using an accelerometer sensor. If a sudden higher acceleration is detected that would mean that the wearer has fallen. Check my MEMS tutorial for this. These sensors are cheap and you might be able to get that effect.

Hey there i’m working on a project on metal detectors anything on the subject?

Hey, sorry at this moment I don’t have anything on that subject.

we are making a project about campus security system..how can we built a system that can lock or unlock door and record our data by scanning smartcard?

You should check my Arduino RFID Tutorial for that purpose. There I explain how to use RFID card to lock and unlock a door, and of course, you could add some more features to it, like recording the date, the time, count the data etc.

You have explained each and every project in detail and simple language. Anybody who knows the basics of electronic science can build the project easily and can enjoy Arduino circuits. Thanks to your team

I got an A in my project. Thanks for such beautifully designed website and arduino skills. Just a beginner at the moment. You rock! : )

That’s awesome! Thanks!

Wondering if your next project should be using a ESP8622, WS2812 strips and a TFT touch display. Many use the adruino webserver to control lights, but why not do it through a TFT to chose the various patterns and effects? Throw the phone aside and have a all in one to control those light!

Yeah, that would definitely be an interesting project.

i am a student working on my final year project which is to design an automated car jack,will use a hydraulic jack for lifting an automobile and i want to use my android phone to act as the remote control,meaning lift of the automobile will simply be done by just pressing the button in app which will be installed on my phone,kindly asking for some ideas on how i can achieve this and the necessary software/app i can use on my phone?

That’s a cool project idea. The main concern if you would like to build a real life example with lifting a car would probably be the lifting mechanism. Otherwise, if you just want to make the concept working with a simpler mechanism, the software/app part of this project would be easily achievable. For that purpose you can check my detailed tutorials, how to use the Arduino with the HC-05 Bluetooth module and how to make your own Android app for controlling the Arduino.

Hi, Shrikant here ,i was working on a project ,i got a problem in my project, the problem is,i am trying to operate big motors using relays ,contactor relay,operated by arduino. The relays does not operate properly ,the loop does not get completed .The relays are not taking load contactor ,i think so. It completed the loop 3 times only. Do you have any suggestion or hint please reply me.

Check my Arduino Relay Tutorial, it might be helpful.

are the relay coils providing a back emf spike as this may upset the arduino , this occurs when power has been interrupted to the coil the way to stop this is to wire a suitable diode in reverse polarity to the emf supplying the coil when it is to be activated , this may have already been done but I thought I’d mention it just in case

jst try to use regulated DC supply. If you are using 9v bat then same problem may occur.

The digital pins may not sink enough current to operate the relays, you may need to use transistors to switch the relays.

Dave is probably right but another way is to use a smaller relay and then pick the large relay with the contacts of the smaller one.

the arduino outlet current is very limmited at most 40m A for all pins toghether,which is means that if you directly connect your relay to arduino, it may damage your whole arduino or the least that pin connected to relay. its better to use optocoupler or transistor or both of them to seperate your high voltage or high current from your arduino. for optocoupler you may connect your arduin pin to optocoupler pin1(anode) ans resistor 330 or 470 ohm between them pin 2(cothode) of optocoupler to gnd pin 3(collector) to 5 or 12 or any voltage your relay work with pin 4(emmiter) to relay dont forget to use flywheel diod for your relay and for transistor arduino pin to base pin and a resistor between them collector to dc voltage emmiter to relay, again dont forget to use flyweel diod

As the next logical step, you can start looking into stuff like expert coder Waren Gonzaga’s LED Music visualizer. This beginner project doesn’t even require extra peripherals or sensors: all you need is an Arduino, a breadboard, a microphone input, and a handful of LEDs, and you can improve the aesthetics of your room with a custom-built music visualizer.

13 Burglar alarm

To detect unauthorized entry into your diy workstation.

One of the best ways to protect yourself from intruders is to set up a theft alarm that goes off the moment its infrared sensor detects a change in its surroundings. Despite its high utility, asmodeus_eous’s burglar alarm is great for beginners, as all you have to do is connect a buzzer, a PIR sensor, and an LCD to your Arduino Uno using a breadboard, and flash the code available on this Hackster repository onto the microcontroller using the Arduino IDE.

12 Automatic pet feeding station

Perfect for pet-owners.

The automatic pet feeding station is by far the project with the most utility for those with furry companions at their homes. Of course, I wouldn’t advise fully relying on a piece of tech to keep your pets fed when you’re away from the house for longer durations. But tinkerer edr1924’s Feed-o-Matic provides a great option if you just wish to treat your pets to snacks at specific intervals. While the DIY pet feeding station may look intimidating to create at first glance, edr1924's step-by-step tutorial on Arduino's Project Hub website will help you get the ball snacks rolling in no time!

11 Gesture-controlled robot

As a bonus, the receiver looks like a slick-gauntlet.

Simple to build and even easier to control, Arduino community member Abdelkadir Chantar's gesture-controlled robot car is a neat project for beginner and intermediate Arduino owners. Ranking pretty high up on the coolness leaderboard, this project requires two separate Arduino boards: one for the hand-mounted receiver and another for the robot itself. Besides that, you’ll need a handful of sensors, switches, wheels, and motors to bring this robot car to life.

10 Fingerprint door-lock

Keep all your project ideas safe behind an arduino-colored lock.

A full-on motion-detecting surveillance system featuring an SBC is a great way to keep a vigilant eye on your surroundings, but you can also throw in an Arduino-based fingerprint lock for added security. Created by DIY Projects Lab on Hackster , this easy-to-follow tutorial requires you to connect an Arduino with a solenoid lock, relay chip, 12V battery, and most importantly, a fingerprint scanner module capable of storing up to 162 fingerprints in its database.

9 Arduino gamepad

Who says you need an expensive controller for gaming.

Despite the solid features available on modern gamepads , nothing beats the satisfaction of building your own controller from the ground up. Luckily, assembling a joystick isn’t all that difficult if you’re using a microcontroller like the Arduino boards, and you can follow this Instructables guide created by ace tinkerer MatthewH . The only caveat is that the project won’t work with the uber-popular Arduino Uno, meaning you’ll have to look into the Leonardo or Micro boards to create this 32-button joystick.

8 Automated chessboard

A battle of wits against ai has never been this fun.

Playing Chess Titans and getting demolished when attempting anything past level 6 used to be one of my favorite non-tech hobbies as a teenager. So, you can imagine my giddiness when I came across Instructables user Greg06’s chessboard that allows AI algorithms to physically move chess pieces across the board. Powered by a tiny Arduino Nano, this amazing project uses electromagnets to change the positions of the computer’s pieces. To top it off, the automated chess board even includes provisions for the AI to physically remove your pieces from the board once it captures them.

7 FPV drone

It even works with a vr headset.

DIY robotic cars are quite popular among the microcontroller community, but this amazing project by talented YouTuber Max Imagination proves that the sky's the limit when it comes to Arduino projects. Fair warning though, this incredible project requires a little bit of soldering and software tweaking for a stable flying experience. But what truly sets it apart from other creations is that it includes a tiny camera module mounted on the front, which lets you see the video footage from your VR headset.

Someone made their own drone with an Arduino Pro Mini, complete with its own tiny camera

Zip around your room in style with this tiny terror.

6 Fitness tracker

Stay in tip-top shape with a little help from your arduino companion.

Fitness trackers and smartwatches are pretty capable these days. That said, a self-built fitness tracker will work just as well if you want to record your workouts. Built by Arduino experts Nekhil R and Shebin Jacob , GetFit is a smart fitness tracker that combines Arduino with the AI facilities offered by Edge Impulse to detect your workout routine. Heck, this fun project even has a mobile app, which you can use to keep track of all your reps and get an estimation of the calories burned through your training regimen!

5 Homemade 3D scanner

An affordable way to get 3d models of real-life items.

Have you wanted to capture precise 3D models of everyday household objects without investing in an expensive camera? If your answer is yes, you’ll have a blast replicating Ardumotive_com’s detailed project on Instructables. Apart from an Arduino Uno, you’ll need to purchase an external webcam and some motors alongside the IO shield required to drive them. You could even ditch the wooden chassis to further simplify the setup procedure.

4 Smart dustbin

Automating your cleaning habits, one dustbin at a time.

If you’re tired of manually lifting your dustbin every time you wish to dispose of your trash, then this Arduino-powered dustbin can be your new best friend. At its core, the project uses an HC-SR04 sensor to gauge your distance from the dustbin. Once it detects a person in close proximity, it triggers a signal to a tiny servo motor to open the lid of the dustbin and shuts it down once a few seconds have elapsed. To make things even better, you can easily modify the distance and time values for the smart trash can via the neatly indented code uploaded by developer psp50 on Hackster.

3 Automatic coffee brewer

Nothing better than waking up to a freshly prepared cup of espresso.

DIY enthusiast Gyula Ősi’s automatic coffee maker proves that you don’t need to be a maestro to brew top-notch coffee. Due to the extensive wiring required for the complex project, it may take more than an afternoon to connect your Arduino board to the temperature sensor, decade counter, LED display, and other components required for the project. But once you’re done, you can treat yourself to a nice cup of coffee whose flavor can be customized to your liking using just your smartphone.

2 Smart garden

Prevent your crops from dying while you're away.

Ever wanted a kitchen garden to grow your own herbs, but are too busy to take care of the plants? Then a smart garden automated by an Arduino should be right up your alley. While it does require decent plumbing skills for optimal results, the IoT Smart Garden post on the official Arduino blog helps you manage your garden from behind your computer screen. For those into coding, you can even program the water pump to automatically irrigate the plants as soon as the soil’s moisture level drops below a critical point.

1 Homemade 3D printer

A step-up from the 3d scanner.

3D printers may have become a lot more affordable in the past few years, but there’s no need to spend thousands of dollars on an expensive printer when you’re just starting out. With a bit of creativity and loads of patience, you can cobble together an Arduino-powered DIY 3D printer from scratch by following this guide created by genius developer Mariano Conde Caballero . Besides requiring hours to carefully assemble the chassis, and taking twice as long to calibrate the printer, this project may prove to be quite a challenge for even expert DIY builders. However, should you persevere, you’ll gain your very own 3D printer that costs a fraction of the premium offerings available on the market.

Unbridled creativity and loads of patience are all you need to make full use of your Arduino

Those were 15 amazing projects that showcased all the cool stuff you could pull off with your Arduino microcontroller. Besides these cool ideas, you can also use the Arduino family interchangeably with SBCs on many projects, including DIY weather stations and FM radios .

But if you’re a complete beginner to the Arduino ecosystem, then it might be a good idea to start your DIY journey by learning the basics of the microcontroller before moving over to simple projects such as making LEDs blink. Alternatively, if you prefer coding to tinkering with circuitry, then you might want to keep things simple by switching to an SBC instead.

Once you have a grasp of Arduino and how to wire up a breadboard , it’s time to put your skills to use and build some projects. Whether you’re a maker, hobbyist, or a student looking for an engineering capstone or final-year project, here are 15 Arduino projects for beginners .

I’ve grouped these projects by category, to make them easier to find.

Arduino LED Projects

The epitome of Arduino is learning how to flash an LED. (Am I right?!) But beyond just sending a HIGH and LOW signal to a digital pin, you can add logic, and additional outputs, and create some pretty cool sequences using Arduino and LEDs. I recommend checking out these projects first if you’re brand new to Arduino and want to practice your new skills.

Featured Arduino Project: Record and Play Back a Push Button Sequence

Another Arduino Project for Beginners uses push-buttons and LEDs to record and playback a sequence.

The concept behind this project can be used for Arduino games, Escape Rooms, or just to show off intermediate skills using Arrays, Debouncing, and Digital I/O. You can get the starter code for this project below.

View the full project here: How to Record a Push-Button Sequence with Arduino

Components You’ll Need for Arduino LED Projects

• Arduino Uno
• Jumper Wires
• Push Buttons

In addition to the push-button sequence project, here are some additional projects using LEDs.

• Arduino Hanukkah Menorah
• Arduino Dice
• Random LED Generator

Arduino Projects Using Sensors

To use sensors with Arduino, you need to become familiar with how to interface them with Arduino digital and analog inputs. Most sensors have anywhere from two to four pins.

Typically, sensors have three pins including ground, power, and signal. You can wire the sensor directly to the Arduino or set up your project on a breadboard.

Featured Beginner Project: Arduino Weather Station

This project uses an  Arduino nano , a  BME280 sensor , and an  OLED display , along with a  breadboard and jumpers to create a weather station. The BME280 sensor captures temperature, humidity, and pressure measurements and sends them to the Arduino via I2C.

Arduino Bluetooth & Communication Projects

The third set of Arduino projects for beginners has to do with Bluetooth and communication protocols (Serial and WiFi). As a beginner, it’s important to learn how to use the onboard features of the Arduino. However, once you understand how to use sensors, the next step is to learn how to communicate with other devices.

In these projects, you’ll explore ways to interface Arduino with Python, Bluetooth Low Energy (BLE), and If This Then That ( IFTTT ).

Featured Beginner Project: Control Arduino with Python

This project sets the Arduino as a Serial device. Rather than using the Serial monitor to send a bit of data, you’ll use a Python script to write 1’s and 0’s to the Arduino.

The Arduino will then turn on and off an LED. You can use this methodology as a starting point for more sophisticated Python projects to control Arduino hardware.

View the full project here: How to Control Arduino with Python

Components You’ll Need for Arduino Communication Projects

• Bluetooth Module

Check out these additional Arduino projects!

• Arduino Bluetooth Car
• Bluetooth Low Energy (BLE) with Arduino
• Arduino with IFTTT

You can also download a copy of our Arduino Project Workbook and have over 20 hours of fun, beginner Arduino projects.

Arduino Motor Projects

The last batch of projects interfaces the Arduino with both servo and DC motors. While you don’t need a motor controller to drive servos on the Arduino, you will need one for DC motors and stepper motors. I recommend the L298N or the L293D chips.

If you plan on driving a bunch of servo motors, you may want to consider an I2C servo driver that has its clock. That way you don’t tie up the Arduino while you’re trying to process multiple signals.

Featured Arduino Project for Beginners: Face Tracking

In this project, learn to control a pan-tilt servo mechanism with your face. We’ll use OpenCV for facial recognition and Python to send position data to an Arduino.

The Arduino is connected via Serial and maps the position data to control the pan-tilt servos. It’s a pretty fun project, that’s sure to impress a crowd. Give this project a try!

View the full project here: Face Tracking with OpenCV, Python, and Arduino

Components You’ll Need for Arduino Motor Projects

• L298N Motor Controller
• Servo Motors
• Potentiometers

Here’s a list of additional Arduino projects using motors.

• Smart Robotic Arm Using Arduino
• Motor Control with Arduino
• Pan-Tilt Servos with Arduino

Once you have a firm grasp on the fundamentals of Arduino , the next step is to work on more advanced topics such as Robotics or the Internet of Things .

6 Of The Best Arduino Nano Projects To Build In 2024

So you've already outgrown Arduino's most beginner-friendly board , the Uno, and are looking to move on to bigger, more exciting projects. In that case, the Nano family might just be what you need. This set of microcontroller boards start around $25 and come in the smallest footprint made by Arduino, allowing you to build compact and portable devices that are more difficult to make with an Uno. However, their size isn't their only major draw. The boards in the Nano family are also equipped with features such as human device interface (HID) functionality, Bluetooth connectivity, and onboard sensors. That means there are many applications you can use these boards for. Add that to the fact that the Nanos are among Arduino's most popular boards, so a quick Google search will pull up a host of tutorials and project guides for you to browse through.

For your convenience, we've compiled six of the best Arduino Nano projects to get you started.

Gesture-controlled mobile robot

The Arduino Nano, compared to the Uno , is the more ideal board for mobile robots as it helps keep the chassis compact. However, if you want to go beyond standard robots, then you might find this gesture-controlled mobile robot  an exciting project to take on.

This robot uses the user's hand gestures to determine which way to move. It can operate in one of three modes: Normal, Drift, and Corner. The Normal Mode makes the robot go forward when your hand is down, move backward when your hand is up, turn left when your palm faces left, and turn right when your palm faces right. Meanwhile, in the Drift Mode, the robot is programmed to only drive sideways based on where your palm is facing, be it left or right. Finally, in the Corner Mode, the robot moves diagonally.

In terms of the hardware, this robot uses an Arduino Nano as the brain, two motor drivers to control the DC motors, a wireless transceiver module to receive signals from the transmitter device worn on the hands, a buck converter to power the Nano, and two 18650 Li-ion batteries. For the transmitter device, a Seeduino Xiao Arduino-compatible microcontroller board is connected to a hand glove, along with an accelerometer and a button for switching modes. On the software front, ChatGPT is used to create the basic framework of the code, which is further modified to fit the project requirements.

Holographic matrix clock

While you typically only see holograms in sci-fi movies and shows, there's a way to bring them to life with the help of Arduino Nano. A beginner-friendly Nano-powered hologram project is this holographic matrix clock . It uses a real-time clock (RTC) module to get the precise date and time. This is then displayed as a mirrored text on an 8x32 LED matrix module and reflected on a thin transparent screen to simulate that hologram effect.

Apart from the cool text that seemingly floats in the air, what also makes this DIY clock stand out is its different display modes. There's the Basic Mode which displays the time in HH:MM format, the Small Mode which uses HH:MM:SS format and a smaller font size, the Slide Mode which looks similar to the Basic Mode but with a slide effect when the time changes, and the Words Mode which flashes the time in words rather than numbers. To change modes, press the first button. You can also use this to change the clock settings, such as configuring it to change the display mode after a set amount of time, switch the time format to 24-hour, and adjust the brightness of the LED matrix. There's also a second button on the clock that displays the current day and date when pushed.

If you no longer want to use your device as a clock, you can replace the LED matrix with your smartphone and have it play 3D hologram videos too.

Voice-controlled bicycle turn signal light

If you typically take your bike around the city, then you already know how hard it is to change lanes or turn a corner. To make your rides safer, check out this voice-controlled turn signal light for your bike.

This helpful bike attachment is designed to recognize when the rider says the words "left" or "right." It then subsequently flashes either the left or right RGB LED strip three times, effectively serving as a signaling device. For reliability and privacy, the command recognition is done completely offline by an Arduino Nano 33 BLE Sense. This microcontroller unit conveniently comes with an onboard microphone, so you need only three main hardware components for the project: the Nano, RGB LED strips, and a power bank.

But while the hardware part is simple, the software aspect is less so. It's based on a word recognition model trained on the AI platform Edge Impulse. The model can distinguish between noises, the words "left," and "right," and other words to avoid false positives. After training, it's then converted into a TensorFlow Lite-powered Arduino library for your board. This library comes complete with example code, which is then used as the framework for the final program.

DIY Photoshop console

Photoshop keyboard shortcuts are a godsend for people who spend most of their days manipulating photos and creating videos on the app. Instead of needing to navigate through the maze of menus to perform specific actions, you can just click a couple of keys. But did you know you can make the process even more efficient with a DIY Photoshop console powered by an Arduino Nano RP2040 Connect?

Unlike the classic Arduino Nano R3, the Nano RP2040 Connect comes with a human interface device (HID) feature that essentially converts it into a mouse or keyboard when connected to the computer. This allows you to use the board to send keyboard shortcuts to Photoshop on your PC. The console is made up of four buttons and two potentiometers, which are assigned with different functionalities. Button 1, when pressed, sends a Ctrl + T key combo to the PC, a shortcut for activating Free Transform. Meanwhile, Button 2 sends Ctrl + U that opens the Hue/Saturation menu, Button 3 sends Ctrl + J that adds a new layer via copy, and Button 4 sends a V that turns on the Move tool. Potentiometer 1, on the other hand, is used for zooming in and out. The creator's code doesn't include any functionality for Potentiometer 2, but you can readily assign one as the sketch is easy to understand even for beginners. You can also modify the keyboard combos of the buttons if you use other shortcuts.

Snoring detector

Snoring may seem harmless, but it's often a symptom of a bigger health concern , including nasal congestion and sleep apnea, which can increase your risk for high blood pressure and a heart attack. That's why it's crucial to know whether you snore or not, so you can consult a healthcare professional as early as possible. But what if you live alone and have no one to tell you about your snoring problem? This is where a snoring detector can come in handy.

Aptly named the Snoring Guardian, this DIY device works by listening to your snores and activating a vibration motor unit as soon as it detects one. It features an Arduino Nano 33 BLE Sense that conveniently comes complete with a built-in microphone. This microcontroller board, along with the motor and the Li-ion battery pack that powers the device, is then enclosed in a simple pouch bag with an opening for the mic. The great part about Snoring Guardian is that it doesn't use monitoring wires that attach to your body, making it non-invasive and easy to use.

Software-wise, the developer used Edge Impulse to create and train the machine learning model that classifies sounds as either snores or noises. The model was trained on different sounds, such as snoring, other human sounds like sneeze, cough, and humming, and environment sounds like rain, silence, and clock ticks. Once finished, the snore recognition model was exported as an Arduino library.

Simple MP3 player

There's nothing wrong with using your phone as a music player, but it isn't always the most convenient choice. You don't necessarily have to buy a commercial device, though. If you already have an Arduino Nano lying around, you can easily turn it into a basic MP3 player and even practice your electronics skills in the process.

The star of this project, apart from the Nano of course, is the DFPlayer Mini. It's primarily an MP3 player module, but it also supports WAV and WMA audio formats. You can insert up to a 32GB microSD card on its onboard card slot and cycle through as many as 25,500 songs. Connected to the DFPlayer Mini is an audio amplifier board module with two external 8-ohm 4-watt speakers and a built-in volume knob. To control the playback, there are four push buttons connected to the Nano. You can use them to switch to the next song, repeat the current track, go back to the previous song, and pause the playback.

The software is pretty straightforward and easily understandable. You generally don't need to change anything in the code unless you want to add new button functionalities like playing only a specific folder or audio file, randomly playing all the MP3 files, and stopping the on-repeat track.
