Legend Of Zelda

Arduino
A demonstration of my MusicWithoutDelay library. It plays the Legend of Zelda and allows the user to pause/play, skip, and reverse the song at any time. Best of all, since it doesn't use delay(), you can easily add more code to it and make it do other cool things, like read the Serial monitor or display on an Oled.
