Working Principle
This module is also 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 and controls the states of red, green and blue LEDs to achieve different color outputs.
- PWM dimming function : Supports PWM (Pulse Width Modulation) technology, allowing users to adjust the brightness of each color to achieve a mixing effect and thus produce multiple colors.
- Connection configuration : The modular design facilitates quick assembly and disassembly, while red anti-reverse insertion 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 required voltage to 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 functions 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.
- G (Green Signal Terminal) : Controls the state of the green LED; it lights up when the signal is high.
- B (Blue Signal Terminal) : Controls the state of the blue LED; it lights up when the signal is high.
