Wiring Diagram

MicroPython code

Using a line following sensor is fun and simple! After you attach the special wires (called Dupont connectors) to your robot, you can make it work with some cool code.

Remember, we need to slow down our robot’s speed so it doesn’t go too fast and miss the line it’s trying to follow. Also, we want our robot to check the line very often, so it can stay on track while moving along the line.
