I am quite new to electronic and I'd like to build a setup plugged with a 12V PS (because there is a water pump in my setup).
But at the same time, I'd like to feed the Arduino VIN with the same power supply. Is it a good practice to use a regulator to go from 12V to 5V for a H24 setup? I mean, will it burn because of too much power dissipation?
If no, how can I supply the Arduino VIN in a more elegant way?
