Staircase Meets Piano Using Arduino


In November 2014, we displayed our first completed project as a club, the Staircase Piano. The idea for the project was given to us by Professor Barry Brown before the club was even formed. Throughout the semester we worked towards putting the piano together for a final presentation before the end of the Fall 2014 semester.

We started out the project only using an Arduino for both the sensor readout and the sound creation. We were creating sounds using pulse width modulation on the Arduino and outputting that signal to a 3.5 mm stereo jack.banner

The sound coming out of the Arduino wasn’t producing quality sound so we looked into other options. We learned that creating the sounds on the fly wasn’t the best idea so we turned to using digital sound files and playing them with a Raspberry Pi. This drastically improved the quality of the sound and it allows us to expand the project in the future.
