Traffic Light Controller using Arduino and Traffic Light Module

The Traffic Light Controller project simulates a basic traffic signal system using an Arduino Uno and a traffic light module. It is a practical and educational project designed to teach students how traffic systems operate and how microcontrollers can automate timed operations.

This project uses red, yellow, and green LEDs (or a pre-made traffic light module) to represent the traffic lights at an intersection. The Arduino Uno is programmed to control the sequence and timing of each light—green for go, yellow for caution, and red for stop—mimicking real-world traffic signals.

The controller operates in a loop where each light stays on for a specific duration (e.g., green for 10 seconds, yellow for 3 seconds, red for 10 seconds). You can enhance the system by adding push buttons for pedestrian crossings, IR sensors for vehicle detection, or even use LCDs to show countdown timers.
