About this product
A 35 mm piezoelectric element that generates a small voltage when it is deformed by vibration, a knock or a sound wave. It is commonly used to detect knocks on a door, table or other solid surface in Arduino and microcontroller projects. The same element can also produce tones when a voltage is applied across it.

How do I connect a piezo element to an Arduino?
Connect one lead to an analog input such as A0 and the other lead to GND. A resistor of about 1 MΩ connected across the two leads helps stabilise the signal. Arduino knock-sensing examples are a good starting point.
Can the same element be used as a buzzer?
Yes. Applying an alternating voltage makes the element vibrate and produce a tone. Keep the drive voltage moderate and check the element's limits before driving it directly from a microcontroller pin.
