Traffic Lights Module (Red, Yellow, Green LED Module)

The Traffic Lights Module is a simple and effective electronic module designed to simulate a real traffic signal system using three LEDs: red, yellow, and green.

It is widely used in Arduino and microcontroller projects for learning programming, timing control, and automation concepts. The module comes pre-assembled with resistors, making it easy to connect directly to digital output pins without additional components.

This module is ideal for beginners, students, and makers looking to build traffic light simulations, smart city models, or basic automation systems.

Its compact design allows easy integration into breadboards and project enclosures.
