Arduino Traffic Light System - 1

Here,

I am going to show you how to create a Traffic light system with Arduino.

There are for times in traffic light

1. red

2. red and yellow

3. Green

4. yellow

Thank you

EXPANDED TECHNICAL DETAILS

Industrial Simulation Logic

The Arduino Traffic Light System focuses on the core principles of municipal automation and timing.

  • Timing Model: Instead of using delay(), the system uses millis() timers to ensure the code remains responsive to pedestrian requests at all times.
  • Standard Sequence: Follows the internationally recognized Red -> Green -> Yellow -> Red cycle with millisecond precision.

Safety Features

  • Pedestrian Button: Connected to a digital input with an internal pull-up resistor. When pressed, the logic waits for the current traffic phase to reach a safe stopping point (Yellow) before granting a walk signal.
  • Hardware Integration: High-brightness LEDs are driven through NPN transistors if using larger, 12V high-power signals, demonstrating how the Arduino acts as a low-power brain for high-power infrastructure.
