I am trying to figure out how to make a simple circuit that I can install into my mailbox that will allow me to see from my house if the mail has been delivered. Ideally, it would involve a switch that activates an LED when the door was opened, and would require a reset action when I retreived the mail out of the box. It would be nice to have it powered by a 9v battery or something equally space conserving. Any ideas? Any solutions? All help will be grealy appreciated...
Thanks,
Chase
