Producing Sound To make some sound we need a speaker, we could connect a Piezo directly to the ESP32's DAC but that wouldn't produce good volume or quality so we add a simple audio amp module based on the PAM8403, full schematic below (click to enlarge); Full explanation of this circuit is available in the video linked to above. A special feature of this project is that Arduino will record the last played set of tones and repeat those tones like a one time record and repeat feature. So far we were […]. Communication between ProtoPie and Arduino. Background: The Arduino can make sounds, but they aren't loud. Their reliability extends from the fact that they are solid state construction so they have very few moving parts. It's the same principle that you used in Project 7 when creating a pulsating lamp via a sine wave, but this time you replace the LED with a piezo sounder or piezo disc. For the both transducer and buzzer, piezo element is placed between two metal plates. In our example we are plugging the Piezo on the pin number 9, that supports the functionality of writing a PWM signal to it, and not just a plain HIGH or LOW value. Buzzer Sounds. A piezo buzzer uses piezo effect to make sounds. This is one that I’ve been excited about for a long time. The piezoelectric effect can be reversed, which is referred to as the inverse piezoelectric effect. Piezo's have the potential to produce very large AC voltage spikes -- ranging upwards of ±50V. To use this buzzer with an Arduino, simply attach one pin to a digital output and the other pin to ground and your Arduino can now play simple tones.
