3.17 Buzzer
A buzzer or beeper is an audio signaling device. An active buzzer will generate a tone
using an internal oscillator, so all that is needed is a DC voltage. A passive
buzzer requires an AC signal to make a sound. It is like an electromagnetic speaker,
where a changing input signal produces the sound, rather than producing a tone
automatically.
