power my arduino from the car battery?
Will it be too many amps?
Will my arduino use the whole amp from the battery
My arduino will be controlling 3 TIP120 transistors.. 1 for each color. The amps o the LED bars ten selfs will be under 1Amp for sure..
Oh, also do i use the place with the circular jack and solder the wires from the battery to the jack connector for my power? Or do I put the car battery wires in Vnn? I'm always confused what Vnn is..
One more clarification, so with the 1/2A Fuse, I just connect the 12V from the battery to either the power jack or vin?
