2.5 Line Tracking Module
The line tracking module detects lines in the surrounding environment, and transfers the
data to the processor. The processor analyzes the data, and sends a command to control the
movement of the wheels.
2.5.1 Working Principle
The TCRT5000 IR sensor on the line follower has a TX and RX inside. If a bright color surface
is detected in front of the sensor, such as a white paper (about 1cm away), most of the IR
rays will be reflected; if a dark color like black surface is detected, most of the rays will be
absorbed, while only a small amount will be reflected. The RX will output different analog
signals according to the intensity of the reflected IR light.
