This 5-channel line follower module adopt ATMEGA328P microprocessor and change analog data get from five TCRT5000 sensors into digital signal in infrared tracking sensor. The different conduction levels of the phototransistor when it passes over black and white lines will generate different output voltages, thus it can easily identify black and white lines.
There are also RESET key and potentiometer that can regulate sensitivity to adjust to different conditions. MCU read and write interface is helpful to transfer data to MCU. The
I²C interface save more spaces. 5V is the work voltage. There are two positioning holes at the module to assemble with smart car or other robots.
