It’s painfully easy to set up a simple piezo speaker circuit with an Arduino. How to Set Up a Simple Piezo Speaker Circuit using Arduino I don’t know who comes up with this stuff, but they’re friggin’ mean. So basically, by shocking the plate over and over really fast, we can make noise. Again, the higher the frequency, the higher the pitch of the noise we hear. The faster you bend the material, the higher the pitch of the noise that’s produced. By adhering a piezo-electric disc to a thin metal plate, and then applying electricity, we can bend the metal back and forth, which in turn creates noise. It uses a material that’s piezoelectric, it actually changes shape when you apply electricity to it. It’s not like a regular speaker that you might think of. We are going to use a piezo buzzer to make some noise with Arduino.Ī piezo buzzer is pretty sweet. At least 12 cm dental floss, with a thick wax coating (mint flavored works best) Ī Quick Intro to Piezo Speakers (AKA Piezo Buzzers)īirds make it, kids make it – it can be music to our ears or pure torture.Arduino board, I am using an Arduino Uno.Our training covers the programming and hardware necessary for you to play audio files (i.e MP3, WAV) using an Arduino and an Audio board. If you want to get an in-depth course on using Audio Boards with Arduino, The limits you should know when using tone().The basics and more of using the tone() function.How to set up a simple piezo speaker circuit.A quick intro to piezo speakers (aka piezo buzzers).This is exactly what you will learn in this lesson: Whatever your audible need, you will likely find the easiest, quickest and possibly the cheapest way to make some noise is using the tone() function and piezo speaker with your Arduino. Do you need to make some noise with Arduino? Maybe a simple tone for an alarm, maybe a beep to alert you when a specific input threshold is met, or maybe to play the Super Mario Brothers soundtrack to entertain your juvenile mind (it’s OK, we are all there, too).
