Working Principle
This traffic light module is based on digital signal control, and its working principle is as follows:
- Power connection : The module is connected to the power supply through the GND and VCC ports. The operating voltage range is 3.3V to 5V to ensure that the LED works normally.
- Signal control : The signal terminal (S) receives input signals from the controller to control the state of the red, yellow, and green LEDs. When the signal is high, the corresponding LED lights up; when the signal is low, the LED is off.
- Connection configuration : The modular design allows for quick installation and removal, while red anti-reverse connection terminals and wires ensure safe connections and reduce the risk of incorrect connections.
Pin Definition
- VCC : Connect to the positive terminal of the power supply to provide the voltage required by the module. Ensure the power supply is between 3.3V and 5V to avoid damage.
- GND : Connects to the negative terminal of the power supply to ensure the module works properly and provides a stable reference power.
- R (Red signal terminal) : Controls the state of the red LED; it lights up when the signal is high.
- Y (Yellow signal terminal) : Controls the state of the yellow LED; it lights up when the signal is high.
- G (Green Signal Terminal) : Controls the state of the green LED; it lights up when the signal is high.
