This video will teach you everything you need to know in order to program a PID line follower for your EV3 robot. In the video, I explain how to measure your target Color Sensor light value; I explain the three aspects of PID line following (Proportional, Integral, Derivative) and the math behind them; I teach you how to apply these mathematical concepts into your own EV3 program; and finally, I teach you how to fine tune your K values so that your EV3 robot is tuned for optimal line following.
