4. Working Principle 

This active buzzer 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, and supports an operating voltage range of 3.3V to 5V to ensure the normal operation of the buzzer.

• Signal control : The signal terminal (S) receives input signals from the controller to control the buzzer's sound output. When the signal is high, the buzzer sounds; when it is low, the buzzer is silent.

• Connection configuration : The modular design facilitates quick assembly and disassembly, while the red anti-reverse insertion terminals and wires ensure safe connection and reduce the risk of incorrect connection.

5. Foot position description 

The module's pin definitions are as follows:

• 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 works properly and provides a stable reference power.

• S (Signal Terminal) : Receives signal input from the controller. The buzzer sounds when the signal is high.

6. Application Scenarios 

Keyes' new 2021 DIY electronic building block active buzzer module is widely used in:

• Education : Used in electronic courses and practical activities to help students understand the working principle of buzzers and signal control.

• Alarm system : can serve as a simple alarm or alert sound source to alert users to specific events.

• DIY projects : Suitable for developing sound feedback projects, such as electronic toys or alarms.

• Experiment : Used in experiments to demonstrate sound signals, facilitating understanding of the relationship between electronic signals and audio output.
