LED Traffic Lights Signal Module

The LED Traffic Lights Signal Module is a small board with a red, a yellow and a green LED arranged like a real traffic light. Each LED has its own control pin and an on-board current-limiting resistor, so you can connect the module directly to an Arduino, ESP32 or Raspberry Pi and start coding light sequences right away. It is a favourite first project for students learning digital outputs and timing.

LED Traffic Lights Signal Module Specifications

• LEDs: 3 (red, yellow and green)
• Operating voltage: 3.3–5 V
• Pins: 4-pin header with R, Y, G and GND
• Resistors: current-limiting resistors on board, no external parts needed
• Logic: active high; an LED turns on when its pin is driven HIGH

LED Traffic Lights Signal Module Applications

• Traffic light and pedestrian crossing models
• Learning digitalWrite(), delays and state machines on Arduino
• Status indicators (OK, warning, error) for projects
• Robotics and STEM classroom activities

What's in the Box

• 1 × LED traffic lights signal module

Tip: Connect GND to the controller's ground and the R, Y and G pins to three digital outputs. Use PWM-capable pins if you want to fade the LEDs instead of only switching them on and off.
