The piezo disc sensor head (see above circuit) will keep A0 of Arduino at 0 V until it’s disturbed. Once the hardware setup is completed, upload the code, and hit the sensor head with your finger. In ...

The humble piezo disc buzzer is much more than something that makes tinny beeps in retro electronic equipment, it can also be used as a sensor. Tapping a piezo buzzer gives an interesting waveform,… ...

A bare piezo disc has a low-current output signal and is thus susceptible to noise from the environment. Since the low current and capacitance of the disc forms a natural high pass filter with a ...

Piezo elements can be crafted into several types of actuators, depending on what the needs are: disc transducers, bender actuators or piezo stacks.
