A breadboard-friendly active buzzer module that produces a loud 2 kHz tone when you apply 3–5V. Unlike a passive piezo element, this buzzer has built-in driver circuitry — no oscillating signal needed, just apply power and it beeps.
Key Features
- Active Buzzer – Built-in oscillator circuit, no AC signal required
- 3–5V Operation – Simple DC power to activate
- 2 kHz Fixed Tone – Loud, clear beep
- Breadboard Friendly – Pins fit standard 0.1" breadboards
Note: This is an active buzzer with a fixed 2 kHz frequency — the tone cannot be changed. If you need variable frequency output, use a passive piezo buzzer instead.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
