Quick Overview
The DIYables active piezoelectric buzzer is a simple sound output component for electronics projects that need audible alerts and feedback. Because it is an active buzzer, it produces a constant sound when powered, making it convenient for alarms, notifications, and status indicators.
This buzzer supports a 3-24V operating voltage range (rated 12V), which makes it suitable for a variety of setups. It can be used in Arduino, ESP32, ESP8266, and Raspberry Pi builds where you want straightforward sound output without generating tones in software.
