Line Finder V 1.1
Line finder helps make line-following robots. Those eye-like sensors on the board are actually IR emitting LED and sensitive phototransistor. When the phototransistor detects the reflected infrared light from the IR emitting LED, it will output a digital signal, which changes from HIGH to LOW.
A line-following robot can sense a black line by IR emitting LED and sensitive phototransistor, then they will send the signal to microcontrollers. Finally, your robot will drive the motor according to the output of the sensors.
