300+ DIY Arduino Projects and Tutorials

Arduino is a popular open-source development board used by engineers, hobbyists and makers to develop electronic projects and prototypes in an easy way. The Arduino platform consists of many development boards like Arduino UNO, Arduino Nano, Arduino Mega, Arduino Pro Mini etc.. all of which are based on the series of AVR microcontrollers.

The below list consist of a large collection of free Arduino Projects from Circuit Digest, including basic LCD interfacing, sensor interfacing projects to advanced Bluetooth and Wi-Fi project. All projects consist of neatly illustrated Arduino circuit diagram and detailed explanation, the relevant Arduino code is also provided for a complete do-it-yourself tutorial.
