Interactive Textiles
Turn up your volume and you'll hear Grande Valse playing as I trace the surface of the paper with my finger. Conductive ink on the underside of the paper is connected to digital pins on the Arduino creating 13 individual capacitive touch sensors. Each sensor's length is relative to its note's duration–resulting in a sort of lithographic human music box. As it turns out, this type of ink isn't well suited for precision work but it is great for quick textile prototyping.
