In this instructable, we are going to construct the circuit and write the code to control the state of three LED's sequentially using the Arduino Uno board.
Arduino Software (Can be downloaded for free from Arduino)
Three LED's (any color)
Three 330 ohm resistors
Wires as needed
Step 1: Schematics, Code, and Demonstration
