Active Buzzer A buzzer, also called a piezo buzzer, is basically a tiny speaker that you can connect directly to an Arduino or use directly to produce sound. You can make it sound like a tone at a frequency you set. Piezo buzzers are constructed by placing electrical contacts on the two faces of a disk of piezoelectric material and then supporting the disk at the edges in an enclosure. When a voltage is applied across the two electrodes, the piezoelectric material mechanically deforms due to the applied voltage. This movement of the piezo disk within the buzzer creates sound
