WHAT IS ARDUINO?
Arduino is a popular open-source development board for engineers and makers to develop electronics projects in an easy way. It consists of both a physical programmable development board (based onAVR series of microcontrollers) and a piece of software or IDE which runs on your computer and used to write and upload the code to the microcontroller board.
Explore below some interesting arduino projects and tutorials based on different types of arduino baords like Arduino Uno, Arduino Pro Mini, etc. These DIY arduino projects for beginners are explained well and you can find the complete guide to DIY these projects with the help of circuit diagrams, source codes and videos. You can also browse below pages to get new arduino project ideas.

// Program: dual_chaser
//
// Description: 12 LED dual chaser. One led moves from left to right
// while the second LED moves from right to left.
// LEDs and series resistors connected to pins 2 to 13.
