we live on a huge hill so big that we generally drive down the driveway to get the mail. My dad asked me to make him a light in his office that would turn on when the mail had come, because he was tired of going all the way down and it wasn't even there yet. as i never could get the receiver/transmitter i was working on so long ago to work, i told him the best i could do was make a light on the mail box that he could look for with his telescope.
the problem is when the mailman is done, he closes the box lol
how do i make an LED turn on when the circuit is broken, then remain on when it is closed again?
thanks
