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.

Parts Needed:

Arduino Uno

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

Figure 1 shows the schematics for this project on a breadboard.

Figure 2 shows the code for this project.

Finally, the attached video is a demonstration of the complete project.
