500+ DIY Arduino Projects with Code & Circuit Diagram

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.
