Arduino Tutorial

Arduino is becoming the most popular electronics prototyping platform because it is very flexible and easy to use. Beginners can start using Arduino UNO boards for simple LED light circuit. Once you learn how to control LEDs with Arduino you start to think of more difficult projects like home automation system, robotics, etc. Possibilities are almost endless and limited to your imagination.

The most expensive part is Arduino itself, programming and auxiliary components are free to choose and experiment.
