555 timer off delay
Hi gang. Can some one point me in the right direction.
This is what I have now. In my truck I have an air comp and air tank setup. I have a home made water cooling setup for the compressor. I have it wired so that the cooling setup water pump starts and stops with the compressor ( the compressor starts and stops automaticly using a pressure switch).
What I need is a curcuit that will allow the water pump to continue running one or two minutes after the air compressor shuts off. The water pump will need to start with the compressor but continue to run a little longer after the compressor shuts off.
I have made one shot timers before with the 555 ic, but can't figure out how to use this timer for what I need.
Any help would be greatly appreciated.
