LED Traffic Light Module (Traffic Light Module) for Arduino and DIY Projects

The LED traffic light module is a compact board carrying three bright LEDs (red, yellow and green) together with protective current-limiting resistors. Its four-pin interface (GND, R, Y, G) lets you connect the module directly to the digital pins of microcontrollers without any complex circuitry. It is ideal for modelling road traffic control systems, building automatic barriers, "smart city" layouts and a variety of entertainment or educational amateur radio projects. Features: Product type: compact indicator module in traffic light style Specifications: three bright LEDs (red, yellow, green), 4-pin connection interface (GND, R, Y, G), built-in current-limiting resistors Purpose: creating interactive models, road traffic layouts, and teaching programming and electronics in projects based on Arduino and Raspberry Pi
