Arduino Traffic Lights

Arduino traffic light simulation with LEDs

A simple Arduino-based traffic light simulation programmed using the Arduino IDE. This project demonstrates basic control of LEDs to mimic real-world traffic light sequences (red, yellow, green), perfect for beginners learning about electronics, programming, and timing control.

Features

• Standard traffic light sequence: Red → Green → Yellow → Red
• Adjustable timing for each light
• Easy-to-understand code, ideal for learning Arduino basics
• Can be expanded for intersections or pedestrian signals

Components Used

• Arduino board (Uno, Nano, etc.)
• 3 LEDs (Red, Yellow, Green)
• 3 resistors (1KΩ recommended)
• Breadboard and jumper wires

How to Use

1. Connect the LEDs to the Arduino as described in the code.
2. Upload the traffic_lights.ino file using the Arduino IDE.
3. Watch the LEDs cycle through the traffic light pattern.
