I need to Delay a 12vdc relay by 5s to 20s max for my mobile tv parking brake switch. Does anyone know how to wire the 555 ic chip or have a schematic for it?
Will that circuit remain on til i shut off the car or kick off in a certain time? I need to delay it a few secs in able for the radio to boot n than sense the ground connection. Can i use a capacitor n a resistor inline.
