Function: Traffic light simulation module with three LEDs (red, yellow, green) for signaling and timing applications in Arduino and microcontroller projects.

LED Colors: 5mm Red, Yellow, and Green LEDs mounted on a PCB in traffic light arrangement.

Operating Voltage: 3.3V to 5V DC – directly compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers.

Current Consumption: ~20mA per LED (with onboard resistors).

Driver Circuit: Built-in current-limiting resistors for each LED; no external resistors required.

Operation: Digital control – each LED can be turned ON/OFF independently via GPIO pins.

Applications: Ideal for Arduino beginners, traffic signal simulation, robotics, STEM education, and timing control projects.
