This passive buzzer is a simple sound-making component for Arduino, microcontroller and electronics projects. Unlike an active buzzer, it needs a changing signal to produce sound rather than generating a tone automatically.
You can drive it with a PWM signal to control the output, making it useful for beeps, alerts and basic tones in maker projects.
A Little Bird tutorial is available for making a sound with a piezo buzzer.
Specifications:
- Power supply needs: 5V
- Interface type: Analog
Jargon buster
Plain-language definitions for the technical terms used above.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
