5V Traffic Light LED Module for Arduino — Red, Yellow, Green (10pcs)
Each module in this 10-pack carries three 5mm LEDs — red, yellow, and green — with individual current-limiting resistors on a compact PCB. Each LED is independently controlled from a separate GPIO pin, and the 5V supply means direct connection to an Arduino Uno or Nano digital output without any external components.
- 3 LEDs per module — red, yellow, green, fully independent control
- Onboard resistors — connect directly to Arduino GPIO, no extras needed
- 5V supply compatible — works with Uno, Nano, Mega digital pins
- 4-pin header — VCC, GND, and two signal lines
- Pack of 10 — covers classroom sets or multi-station builds
How do you wire the traffic light module to Arduino?
Connect VCC to Arduino 5V, GND to GND, and the LED signal pins to digital output pins. Set each pin HIGH to illuminate the LED, LOW to extinguish it. No resistors or transistors are needed — the onboard resistors limit current to a safe level.
Can you PWM-dim the LEDs?
Yes. Connect the signal pins to Arduino PWM pins (3, 5, 6, 9, 10, or 11 on Uno) and use analogWrite() with values from 0 to 255. Each LED dims independently for speed or status visualisation.
Best for
Arduino traffic light simulations, STEM classroom GPIO exercises, robot status indicators, state machine visualisers, conveyor lane signals, queue management displays, and beginner LED control projects.
