Grove - Line Finder v1.1

Grove-Line finder is designed for a line-following robot. It has an IR emitting LED and an IR-sensitive phototransistor. It can output a digital signal to a microcontroller so that the robot can follow a black line on a white background or vice versa. Those eye-like sensors on the board are actually IR emitting LED and sensitive phototransistors. 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.
