Hi!
As title says is there some special design considerations for electronics installed in car?
I need something to turn on the amplifiers with little delay since my line converter is acting wonky and outputting startup signal ie. When door is opened and the amplifiers briefly try to start because of this, which is not wanted, manufactor of the line converter washes his hands by saying "it's so new car that it might give all kind of signals"...(great).
So I was thinking, adding atmel to highjack the signal from line converter and turn on the amplifiers via relay or something when the signal have been active for X amount of time, thus eliminating the false signals.
