4. Working Principle
The active buzzer module operates based on digital signal control:
- Power Connection: The module connects to a power supply via GND and VCC ports, operating within 3.3V to 5V to ensure proper functionality.
- Signal Control: The signal pin (S) receives input from a controller. A high-level signal activates the buzzer, while a low-level signal silences it.
- Connection Configuration: The red anti-reverse connector and matching cable ensure safe and efficient connections, minimizing wiring errors.

5. Pin Description
| Pin Name | Description |
|----------|---------------------------------------------------|
| VCC | Positive power supply (3.3V to 5V input) |
| GND | Negative power supply connection |
| S | Signal input pin for controlling buzzer activation|

- VCC: Connects to the positive terminal of the power supply. Ensure the voltage remains within 3.3V–5V to prevent damage.
- GND: Connects to the negative terminal (ground) for stable operation.
- S (Signal Pin): Receives control signals from a microcontroller. A high-level signal triggers the buzzer.
