Arduino is a popular open-source development board used by engineers, hobbyists, and makers to develop electronic projects and prototypes easily.
The below list consists of a large collection of free Arduino Projects that was built by us here in Circuit Digest. All the projects that we have provided here consist of neatly illustrated Arduino circuit diagrams and detailed explanations, the relevant Arduino code is also provided for a complete do-it-yourself tutorial. If you want more projects you can also check out our collection at Arduino IoT Projects | Arduino Robotics Projects | Arduino AI Projects | Arduino Home Automation Projects | Raspberry Pi Projects | ESP32 Projects
