Hello, I am helping my daughter make a book for a school assignment and she'd like to make a single LED light up when one of the pages is opened. I have an LED and a button battery (3V), and I can make it light up when the anonde/cathode are attached to the button cell. But I have no idea how to make it go on and off when the page is opened/closed. Can anyone help me with this? A big thanks in advance!
