It's been a long time since I've been in the world of dc component based circuits. My stay in the land of plcs and programmables has left me dumb to the basics of dc circuits. I would appreciate any help offered on this circuit.
The circuit is supposed to light the led when the switch is closed.
If the switch is closed for more than 1.2 seconds the led will go out.
The led to stay lit for .5 seconds after the switch is opened.
This should allow a pulse of 2 hertz or greater to keep the led lit but prevent it from staying lit if the circuit is stuck high.
Thanks for any help,
Matt
