I am thinking of creating a circuit that lights up a green LED once the garage door is open so I don't need to lean out the car window to see when the garage door is open all the way. A switch will be triggered once the garage door is all the way up. But if I leave the garage door open for more than a couple of seconds, or even minutes, then the LED should stop shining so the battery doesn't drain, and once the circuit is open (garage door is closed) it should 'reset' so that it lights up the next time I open the garage door.
I want to use basic electronic components, and no chips.
I've tried something similar to this:
I've used software to try and emulate but.. I've more or less lost my train of thought.
I've tried this in the circuit designer:
Once I click the switch into closed it lights up, but when I click OPEN and wait, then click to close the circuit it seems the capacitor isn't discharged and led doesn't lit up.
What's the best way to go about this?
