The Arduino here creates tones of different frequencies, playing them through a connected piezo-speaker. The variation of the frequency of the tone (pitch) and the correct timing (rhythm) create the ...

A simple melody library for a piezo buzzer. Most of the arduino examples use a delay to control note length. This blocks the loop until the note finishes which isn’t practical in most applications.

Arduino-Buzzer-Tune-Play-a-Melody-on-Loop- In this beginner-friendly tutorial, I'll show you how to create a simple project where a buzzer plays a tune on loop using an Arduino. This is a perfect ...
