For this lab, I took a wooden stick, put an accelerometer at one end of the stick, and put a small button at the other end of the stick. As you can see in the photo in the zip file, I used ribbon cable to connect the accelerometer to the board and stranded wire to connect the button. To play this instrument, you hold the wooden stick as if it were an hour hand on the clock (the button being in the center and the accelerometer on the circumference), rotate the stick to set the pitch, and press the button to produce the pitch. As you can see Ben's YouTube demonstration of my instrument, I mapped the pitches such that middle C is mapped to the 9:00 position, and the C one octave above is mapped to the 12:00 position. To make it easier to play Twinkle, Twinkle, I limited the pitch space to integer-valued MIDI keynums.
