If you have an Arduino, you may have run into a project that required the board to make sounds. One of the cheapest and easiest ways to accomplish this is to use a Piezo Buzzer.

Piezo Buzzers are extremely simple to wire, and have very simple code.

This video explains how a Piezo Buzzer works, how to use it, and how to wire/code it.

If you have any questions, leave one here or on the video and I'll get to you as soon as I can. Enjoy!

I love this one. Easy, useful and fun. thanks for the project.
<p>this is really helpful for this project I'm doing at school!</p>
