LED Traffic Light Module

The LED Traffic Light Module is a compact and high-quality mini traffic light designed for educational, prototyping, and hobby electronics projects. Featuring three 5mm LEDs in red, yellow, and green, this module is perfect for creating a traffic light system model, demonstrating automation concepts, or integrating into school science and engineering projects.

Compatible with Arduino and other microcontrollers, the module is simple to wire and can be controlled using digital signals or PWM (Pulse Width Modulation) for brightness adjustment. This makes it ideal for simulating real traffic light operation and learning how traffic robots and junction control systems work.

By using multiple modules together, you can simulate a complete traffic intersection with four junctions, offering a hands-on way to understand programming logic, sequencing, and electronics.
