Hello all.I want to build a circuit that will give an output adjustable from 5-15 seconds from a 3v positive pulse that lasts approx. 3 seconds.Preferably I would like the circuit to respond again after the pulse is removed and applied again.I am thinking a 555 would be in here somewhere,but I am too busy to think this one up, :oops: ...so I will leave it to you fine folks,thanks for the help.
:p
P.S.-The output will go through a transistor that would drive a relay. :wink:
