The active buzzer has built-in electronics that produces the buzzer sound. For this reason it will sound when power is connected to it and does not need any external electronics or an Arduino for it to produce a sound.

Description
The Active Buzzer Module is a straightforward audio solution for projects needing a consistent audible signal. Featuring a piezo buzzer with an integrated oscillator, it produces a fixed tone—typically around 2.5kHz—when powered at 3-5V, making it ideal for alerts or confirmations. Unlike passive buzzers, this active model requires only a steady DC high signal from a microcontroller like Arduino to buzz, simplifying control without the need for complex waveforms.
Mounted on a small PCB (often around 22mm x 12mm), the module uses a three-pin interface: signal (S), power (VCC), and ground (GND). It draws a modest current, typically under 25mA, and is housed in durable plastic for reliable operation. Perfect for beginners or applications where a single tone suffices, it can be enhanced with a transistor for louder output if driven directly from an MCU pin risks overload (e.g., above 20mA). From alarms to user feedback, this module offers a plug-and-play audio device in a tiny package.
