Overview

Product Overview

The KY-006 Passive Piezo Buzzer Module is a simple sound output module for Arduino projects that lets you generate beeps, tones, and melodies by driving it with a PWM signal. Because it is passive, you can control the frequency yourself, which makes it great for alarms, timers, button feedback, sensor alerts, and fun sound effects in STEM builds. It is a quick way to add audio feedback to projects without needing a speaker amplifier.

Questions & answers

Frequently asked questions

Does the KY-006 buzzer work with Arduino or Raspberry Pi?

It is designed for Arduino sound-output projects and can also be used with Raspberry Pi or other controllers that can drive a GPIO/PWM signal. Code support and wiring depend on the board you use.

Is the KY-006 buzzer ready to plug into projects?

The module is intended for quick breadboard or jumper-wire setup, with pre-soldered headers from ShillehTek. Connect signal, power, and ground, then drive the signal pin from your controller; no speaker amplifier is needed.

What signal does a passive piezo buzzer need?

This is a passive piezo buzzer, so it needs a changing drive signal such as PWM or a tone output. The tone frequency comes from your code; a steady DC signal will not create normal melodies.

What projects use the KY-006 passive buzzer?

Common uses include alarms, countdown timers, button-click feedback, sensor alerts, and simple melodies in STEM builds. It is useful when a project needs basic audio feedback without adding a speaker and amplifier circuit.

Why is my KY-006 buzzer not making sound?

Check that the signal, power, and ground connections match your board, and confirm your code is generating PWM or tone output. Because it is passive, test code written for an active buzzer may not work correctly.
