When learning the microcontroller, you may usually use three separate LEDs, namely red, green and yellow light, to simulate the traffic light blinking via external connection.
Convenient for wiring, we specially design this traffic light module. On the module, it has integrated three LEDs, like LED-R, LED-Y, LED-G.
This module is able to make some light-interactive works, fully compatible with Arduino microcontroller and raspberry pi system.
Connect the traffic light module to UNO board, R pin to Digital 5, Y pin to Digital 4, G pin to Digital 3, GND to GND.
