Page Detection and Turn on/off Concept

A project log for Notable Board Books

How alert and happy my mother (with Alzheimer's) became when she heard familiar songs! Lift the book, turn the page--the book does the rest.

By placing holes in the pages that correspond to photo resistor locations, a processor can tell which page is open.

As more pages are opened, more photo resistors detect light. The "deepest" active page is the one that will be played.

Four roller ball tilt switches, placed in a 3d printed enclosure, will be "off" when the book is lying on a table. In any other position, they will be "on."
