hi,
I am working on a project which involves one these http://www.ebay.co.uk/itm/1PC-New-1...al_Components_Supplies_ET&hash=item53fbbb2362
its based on a 555 timer, now to cut a long story short, what I need this to do is when the power is disconnected and reconnected very fast I need the timer to re-start basically I have the input in connected to both NC and NO sides of a relay in the hope that when the relay is powered (by a microswitch as a end of travel switch) it resets the time delay so waits for 10 seconds and when the relay is disconnected it does the same thing. its very hard to explain
thanks, jonathan
