So for our Intro to Physical Computing class we learned how to make simple tones and notes using just the arduino. I attached three pressure sensors to communicate with my laptop and output a note to the attached speaker. To make things a little more interesting I decided to play a song. Rather than choosing something like Old McDonalds or Happy Birthday, I opted to choose something a little more current. So below is a video of me playing along to Snow Patrols Chasing Cars. Im not a huge personal fan or anything, but hey its only three chords and crazy easy to play. Enjoy Snow Arduino, haha, god Im such a nerd.
