Hello all,

I'm working on making a book that uses electrically conductive media, and I'm sort of modeling it after this one: Elektrobiblioteka / Electrolibrary on Vimeo

I was wondering, would any of you happen to know—or be able to make a very educated guess at—how the arduino program knows which page the user is currently on?


Looks as if the creator has used conductive paint to form contacts which are opened and closed as the pages are opened, and has carefully designed the switches so that each page when open produces a unique combination of switch states. It's not completely obvious, but I would guess the contacts are close to the spine since the solution doesn't seem to rely on the free edges of the pages being in good contact.
