This is a digital book reader. When the front cover is opened, a photosensor reads HIGH to display the title page. The page is attached to a motor, which in this case is used backwards as a generator and switch. When the page is turned, it rotates the motor, causing an input pin to read HIGH and provide electricity to generate the next page’s text on a digital ink display. Everytime you turn the page 360 degrees, you generate a new page, so it simulates turning the pages of an analog book. The text (which in my case will be displayed in Processing) has a feature to save a section of the page as an image in the margin by drawing a box around it. You can view that image full-screen by clicking on it in the margin.
