Piezo Buzzer Large Covered

The Piezo Buzzer Large Covered is a large piezoelectric buzzer with a protective cover around the piezo element. The cover shields the thin ceramic disc from damage and forms a small sound chamber that helps project the sound. Piezo buzzers draw very little current, so this one is a simple way to add alarms, warning beeps and alert tones to electronic projects.

Tip: Piezo buzzers come in active types, with a built-in oscillator that beeps from plain DC, and passive types that need a square wave. To check this one, connect it briefly to 5 V: if it beeps on its own it is active and can be switched on and off; if it only clicks, drive it with a square wave, for example the Arduino tone() function.
