20 Awesome Arduino UNO Projects That You Must Try 2022!

1. Arduino Music Instrument

Ref: LanmiLab

Want to use gesture control and handwaves to control your Arduino UNO R3? With this Arduino project, you can make that come true! Through this project, you will be using a board called Flick which is a PCB that is able to detect your gestures from up to 15cm away in 3D space. Draw a circle, swipe your hand – Flick will track it.

With Flick, the possibilities are endless! You can now control your computer, TV, music system, and many more with a Flick of the Wrist! In this Arduino UNO R3 project, we will be using Flick with the Arduino UNO to create a musical instrument!

3. Arduino Robot Car

Ref: Black keyhole

Obstacle Avoiding Robot is an intelligent device that can automatically sense the obstacle in front of it and avoid them by turning itself in another direction. This design allows the robot to navigate in an unknown environment by avoiding collisions, which is a primary requirement for any autonomous mobile robot. The application of obstacle avoiding robots is not limited and it is used in many military organizations which helps carry out many risky jobs that cannot be completed by any soldiers.

It uses an Arduino micro and OLED display to make a tiny gaming console, even smaller than the GameBoy pocket. This is an arduboy compatible system which is an 8 bit, credit card-sized gaming platform, that makes open source games easy to learn, share and play. You can play games made by others or you can also design your own games for it.

What do you need?

  • 1 x 5-way tactile switch
  • 1 x Arduino micro
  • 1 x SPI OLED Display
  • 1 x slide switch
  • 1 x buzzer
  • 1 x Tactile switches

6. Arduino UNO Car/ Truck Simulator

Inspired by Silas Parker

Do you know there is a technology called CAN (Controller Area Network) can be used to allow microcontrollers and devices like the Arduino to communicate with each other within a vehicle without a host computer that allows for control and data acquisition? Want to find out more? You can check out our guide for an Introduction to CAN-BUS and How to use it with Arduino!

Through this project, we are going to make use of CAN technology and create a car/truck simulator with a real dashboard on your PC with the UNO and a CAN-BUS Shield!

8. Laser Tripwire Alarm Security System

Ref: SurtrTech

Security systems are often expensive to set up and also expensive to maintain. Why not create yourself with an Arduino together with a few other modules for less than $30!

Through this project, you will create a laser tripwire alarm system where once the laser beams are cut, the alarm will go off and will not stop until a button is pressed. In addition, you can also set up a passcode to make it even more secure where it now requires a passcode entered into it to stop the alarm.
