My brother asked me to make a traffic light for his LEGO's town.

EXPANDED TECHNICAL DETAILS

Mechanical & Electronic Fusion

This project integrates standard LEGO bricks with Arduino-based electronics to create a functional urban simulation tool.

  • Form Factor: The traffic light housing is built entirely from LEGO Technic or standard blocks, featuring transparent or translucent pieces for the Red, Yellow, and Green lights.
  • Lighting Control: High-brightness LEDs are embedded within the LEGO structure, driven by the Arduino's digital pins. It implements the standard international timing sequence (Red -> Green -> Yellow) using millis() for non-blocking operation.

Scalability

  • Pedestrian Interaction: Includes a small LEGO-compatible pushbutton to simulate a crosswalk request.
  • Learning Outcome: Serves as a perfect introduction to automation, showing how simple code can control physical physical structures in a "mini-city" environment.
