Feature

High Grade - Uses the MCU ATMEGA328P as the controller and the TCRT5000 infrared photoelectric sensor on each of the 5 line follower modules.
Less Interfaces - Adopt I2C ports which only occupies 4 pins of the MCU.
High Accuracy - The sensor TRT5000 is highly sensitive with reliable performance.
Easy Assembly - With two 3mm positioning holes on the board for easily assemble with other robots.
Adjustable Sensibility - A potentiometer is added to adjust sensitivity if the signal of the black lines is too weak to detect. Normally you don't need to adjust.

Description

Introduction
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 IC 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.
