Module description: The tracking module is used to transmit light to the road by the infrared
transmitting tube. When the infrared light encounters black, it is absorbed. The receiving tube
does not receive the reflected light and outputs high level. When the red light meets other
colors, the receiving tube receives the reflected light and outputs a low level. When using analog
output, the module can be used as a gray-scale sensor. The gray-scale sensor is an analog
sensor, which can sense different colors of the ground or desktop and generate corresponding
signals.
