Make Homemade Piezo Christmas Songs

Introduction: Make Homemade Piezo Christmas Songs

For a digital Christmas, let your Arduino play songs with a piezo buzzer.

I wanted to make a funny Christmas project. Since I'm just starting with Arduino and I only have the parts from the Starter Kit, it had to be something easy. I came across the Super Mario theme with a piezo buzzer project from Romeo Hackster . I decided to recreate it.

First step was adding push buttons, one for every song.

    Nice project except your code because you didn't follow the DRY principle.
