RGB Line Follower

Basic knowledge of RGB line follower

The RGB Line Follower module is designed for line patrol competitions. It contains 4 RGB fill

lights and 4 photosensitive receiving tubes. The module has a learning button and an LED indicator on

the front. The learning button is used to learn the background color and the track color of the arena. There

are 6 fixable screws through holes at the installation position and a RJ25 base is at the tail. The module

can be applied to dark background with light-colored tracks, or light-colored background with dark tracks.

The RGB Line Follower needs to learn the arena through the learning button, so that it can adapt to

external environments of different heights, light and other factors. The module port is marked with a

blue and white label, which indicates dual-digital and I2C port that needs to be connected to the port with

a blue-white mark on the main board, as shown in Figure 1.
