How to Tell an EV3 Line Follower to Stop – Programming Loop Exits in EV3-G

So you’ve made an awesome EV3 line follower program that can follow the line smoothly and reliably, but there’s still one problem… how do you get your robot to stop line following when you want it to? In today’s EV3 programming tutorial, I will teach you how to use the EV3 color sensor to program loop exits for your EV3 line follower program. They allow your robot’s line following program to exit the loop and move on to the next part of your program when a certain condition is met. This is especially useful if you are using a line follower for your FLL robot.
