Arduino: Simple Sequential LED's

Reproduced from https://www.instructables.com/Arduino-Simple-Sequential-LEDs/

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)
Breadboard
Three LED's (any color)
Three 330 ohm resistors
Wires as needed

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.
