The traffic light module integrates three different color LEDs: red, yellow, and green. It has four pins, one of which is a common pin, and the other three pins control the operation of three different color LEDs. The common GND is connected to the GND port of the development board, and the R, Y, and G pins are connected to different I/O ports of the development board. When each R, Y, and G pin inputs a high level, the corresponding color LED will light up.
