Arduino Traffic Light Control System

This project simulates a traffic light control system using an Arduino and two sets of traffic lights. The lights change between red, yellow, and green, with adjustable durations for the different lights.

Components

• Arduino Uno (or compatible)
• 6 LEDs (2 red, 2 yellow, 2 green)
• Resistors (220Ω recommended)
• Breadboard and jumper wires

Schematic diagram

Circuit

• Traffic Light 1 (Red, Yellow, Green): Connected to pins 10, 9, and 8.
• Traffic Light 2 (Red, Yellow, Green): Connected to pins 7, 6, and 5.
• The LEDs for both traffic lights will alternate, with one set showing red while the other shows green.

How it Works:

1. The system starts with both traffic lights initialized. One will display green while the other displays red.
2. The lights change after a set duration: green or red lasts for 10 seconds, yellow lasts for 3 seconds.
3. The cycle alternates between the traffic lights, ensuring synchronization where one shows red while the other shows green, and vice versa.
