8mm Yellow Green Red Led 5v Module

This traffic light module features three 8mm LEDs (Red, Yellow, Green) mounted on a compact PCB, designed to operate at a standard 5V supply voltage. It includes a 4-pin header for easy connection to microcontroller boards such as Arduino, Raspberry Pi, or NodeMCU, with dedicated pins for Ground and each LED color. The module supports both digital and PWM signals, allowing for individual brightness control of each LED. It is ideal for creating traffic light simulations, status indicators, or educational electronics projects.
