LED Traffic Light Signal Module with Red, Yellow, Green 5V
The LED Traffic Light Signal Module is a compact, breadboard-friendly expansion board engineered for simulating automated crossing systems and roadside indicators. Driven by common-cathode electronic paths, this high-performance display block integrates three distinct high-brightness 5mm LEDs mapping standard Red, Yellow, and Green traffic light arrangements. It eliminates the layout complexity of wiring separate resistors by housing independent internal current-limiting safety networks for each light path. Operating on a standard 5V DC power supply, each color pin triggers via a simple digital high/low GPIO signal—making it the definitive component choice for smart city automation layouts, autonomous miniature vehicle check-points, university microcontroller coding labs, and DIY interactive model train grids driven by Arduino, ESP32, or Raspberry Pi.
