WebAug 14, 2011 · The piezo effect works both ways: if you apply a voltage the piezo stretches, but also if it stretches it creates a voltage. This principle is used to create a feedback signal which drives the oscillator. The … WebSep 14, 2024 · The buzzer is a small component with a piece of metal in it that moves when you apply a voltage across it. This motion causes a small sound, or “click.”. If you turn the voltage on and off fast enough, you get different beeps, squeals, chirps and buzzes. You will use PWM to control the speed of turning the piezo on and off — and, in turn ...
