Most of automated robotic projects start from a line-following robot, Grove - Line finder v1.1 is designed to achieve this task easily and quickly. 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.

Integrated indicator LED
Adjustable detecting range.
Power supply: 5V DC
Digital output mode: TTL (High when black is detected, Low when white is detected)
Connector: 4 pin Buckled Grove interface
Photo reflective diode: RS-06WD
