I need to figure out a way to do the following. (I’ve tried 555 circuits, transistors , not gates and arduinos with transistors etc and can’t seem to figure it out.) The problem is that the led doesn’t flash then go off. It’s the ability to turn off the LED after about 1 millisecond that is the problem. Can anyone help?
(1) My (switch) needs to be a break in ground.
(2) Turn on a 12v LED when the switch opens (breaks ground)
(3) LED flashes for about 1 millisecond and turns off
(4) the switch will then close and the LED should stay off
So in other words I need a 12vdc LED to flash about 1 millisecond when the ground circuit opens up then goes off until the ground opens again. I'm open to using transistors, timers, arduino in combination with other components. Thanks for reading.
