Let’s begin!

A buzzer consists of an outside case with two pins to attach it to power and ground.

A piezo buzzer

When a voltage is applied to the buzzer, it causes an internal disc to vibrate and you can hear the sound. By changing the frequency of the voltage supply, the speed of the vibrations changes, which changes the pitch of the sound.
