The Piano Box: using CapSense with Paper by @catlx

Our friend Catarina came up with this neat project called “Piano Box“, which uses capacitive sensing to make a paper piano keyboard, then generates the appropriate tones using the Tone library on the Arduino. From the NYCR blog:

The piano box is a (somewhat polyphonic) paper toy synthesizer with 12 keys, each triggering a tone and an LED. The keys are a set of capacitive sensors, made of copper tape, controlled by an Arduino Mega running the CapSense and Tone libraries. The code for this project, written by Will Byrd and Catarina Mota, can be downloaded here. Please note that the current version of the Tone library has some problems on Arduino 1.0. so it’s best to use version 23 or earlier.

The libraries used are available here:

The first thing I thought of when I saw this was the roll-up piano from that TNG episode. I love the idea of using cap sensing and paper — it opens up a world of possibilities for user interaction without prohibitive costs! Nice work, Catarina!
