Hello, First post but not last.
I am needing help with a circuit I have in mind. I want to use a LDR to activate a LED but I need the LED to stay on until light strikes the LDR again.
Basically:
Box lid closed= LED off
Box lid opened and closed= LED on and stay on
Box lid reopened and closed= LED off until box lid reopened.
Cycle begins with lid closed and LED off then, open lid LED on stay on, open lid again and LED off stay off, repeat
I studied electronics when I was in the service 20+ years ago and don't remember much.
Any help or suggestions are greatly appreciated.
