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.
Features
Easy to use
Integrated indicator LED
Digital output
Adjustable detecting range.

Grove-Line finder is designed for line-following robot. It has an IR emitting LED and an IR sensitive phototransistor. It can output digital signal to a microcontroller so that the robot can reliably follow a black line on white background, or vice versa.
