What You Should See
Once you have uploaded the code to the RedBoard, try lightly pressing on the soft potentiometer. You should hear some musical notes from the speaker!
Want to play a song? How about Twinkle, Twinkle, Little Star ('C' is the first 'C' on the left in this case):
C, C, G, G, A, A, G (hold)
F, F, E, E, D, D, C (hold)
F, F, E, E, D, D, C (hold)
