About this project
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 Dipto Pratyaksa. I decided to recreate it.
First step was adding push buttons, one for every song.
Next step: learning how to convert sheet music to code. With the instructions Nathan Seidle provided on his Github, I successfully converted the sheet music from three classic Christmas songs: We wish you a merry Christmas, Jingle Bells and Santa Claus is coming to town.
Don't forget to include the pitches.h file, you can find it here. (The second set of code on the page).
Have you tried to recreate my project? I would love to see your pictures or videos.
