“I wanted to make a project that combined two of my favorite subjects: science and music. I thought of all of the ways that I could combine the two domains, and, I thought that it would be interesting to make an Arduino play Fur Elise while displaying the pitch of the note in Hertz. Now that I have given you an introduction, let’s start building the machine!
You will need one Arduino Uno or Mega, a lot of jumper cables, a Piezo buzzer, a breadboard, a 16*2 LCD screen with all wiper pins in place, and a 10k Potentiometer (you may also hear them being referred to as potmeters). It is best to get all of these supplies together before we start the build.”
