Ok if I catch what your saying the pots are interchangeable to give me the 10sec on 60sec off i need then once the resistance is determined on the prototype then test with an similar resistors. Good to know the IC can handle 6 of these circuits that would be my next question if I need to expand it further. As for the power what decoupling components would you suggest? As for the trigger, Im still playing with some options, but I need to pull liquid from the containers so it is most likely going to be a float switch or continuity sensor so Im probably going to need a signal voltage from this as well, to apply to the trigger. and as far as the FET drains to ground I would just put a diode on each ground for each circuit right?
