Hello from boat engine I get a signal of 12V and 2A. I want to drop the voltage to 5V. For that I will use the voltage divider. Less heat is better, that why I want large resistence resisiors, since the current is high. So which resistors should I choose. Bigger is better? But not too big, since Ar…

Arduino minimum current
