How does a buzzer work in a circuit
WebAug 18, 2016 · A buzzer that is not a piezo based device is a coil relay in which the coil circuit is normally closed. When the buzzer is energized, the relay activates and then opens the circuit, deactivating itself. The cycle repeats, … WebHow It Works. If connecting VCC to the positive pin, piezo buzzer generates the constant sound. If generating a square wave of the specified frequency (and 50% duty cycle) on the positive pin, the piezo buzzer generates tones. The different frequency makes a different tone. By changing the frequency of the signal on the positive pin, we can ...
