Introduction: Arduino: Simple Sequential LED's

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.
