Simplest Piezo Driver Circuit Explained

Last Updated on January 2, 2024 by Swagatam 45 Comments

piezodrivercircuit1

In the previous post I explained a piezo transducer element and learned how to use it with electronic circuits. In this article we will see how a piezo tranducer can be driven or operated using a simple circuit. As discussed earlier a piezo transducer basically requires a frequency to vibrate and reproduce the required sound. […]
