Is there some sort of circuit or switch that would send a .2 second (aprox) positive pulse when power is applied.......
And then send a .2 second (aprox) negative pulse when power is removed?
I realize the negative pulse when power is removed might not be possible so alternatively.
Is there something that would send a .2 second positive pulse when power is applied and then some duration later (between 10 minutes and 30 minutes) send a .2 second negative pulse?
What would such a thing be called if it does exist so I can go searching for it?
