Was working better earlier but the tilt switch sometimes refuses to work without me flicking it angrily. This is a concept for a digital book that powers an electronic paper screen with each turn of the page (in this case an LED). Pages are refreshed with a combination of a tilt switch and motor input. The Processing display has been edited out of the video because of inconsistencies. Arduino:
