Grove - Line Finder v1.1

Most automated robotic projects start from a line-following robot, Grove - Line finder v1.1 is designed to achieve this task easily and quickly. 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. Highlighted Features Integrated function: An IR indicator LED and an IR-sensitive phototransistor Digital output: A digital signal will change from HIGH to LOW. High when black is detected, Low when white is detected Easy to use: Compatible with Grove port, just plug-and-play Flexible detection: The detecting range is adjustable Applications Delivery Robotics Mini Toy Car
