Arduino Line Follower Robot Circuit uses sensors and motors. IR sensors look at floor all time. They find black line and white area. Arduino read these sensor signals. Then it tell motor driver what to do. Motor driver control wheels speed and direction. Robot follow black line by itself. Arduino Coding: Code Explanation: Circuit Diagram: […]
