In this video, we will describe the most simple circuit to drive an AC waveform at ultrasonic frequencies to a piezoelectric element. The essential components of this circuit are a resistor and a MOSFET used as a charge draining switch.You will need a signal source; I used a function generator, but an Arduino will work just fine.
