How can I make an LED proposal ring box power on when open? Answered
I was intrested in placing an LED in a ring box, so that when I open it, it would shine on the ring. I cant figure out how to make it power on when opening and turn off when closed. Does anyone have any suggestions? I thought of maybe using the circuit board from one of those greeting cards but I dont think that would work?
Here is an example of what I'm trying to do: http://www.jna-shop.com/index.php?main_page=product_info&products_id=7241
