How to Program a Proportional Line Follower – EV3 Programming Tutorial

This EV3 programming tutorial will teach you how to make a proportional line follower for your EV3 robot. I will be explaining how a proportional line follower works and walk you step-by-step on how to build one. This will be an extremely useful program for FLL, WRO or any other application where a reliable line follower is needed. You will be able to use both an EV3 color sensor or a HiTechnic Color Sensor V2.
