I am just getting started in electronic circuts, and i have a few questions that might seem alitle dumb. First off I am creating a circut for my car, I need to have a push button activate a few relays, but i need it to close one relay at a time (push: close #1
, push open #1
, and goes on up to 4 then starts back at 1) is there an ic that will do that? Also do i need to put a resister before/after a relay on the coil side, or will the coil have enough resistence not to overload the control circut.
Thanks for the help,
