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
