How to Program a Proportional Wall Follower for EV3

In today’s EV3 programming tutorial, you will learn how to make a proportional wall follower for your EV3 robot. This will work with either an EV3 Ultrasonic sensor or an EV3 Infrared sensor. Applying proportional logic greatly improves the EV3’s ability to follow the wall. This is also very useful for FLL robots.
