Were working on a project were we need to power the arduino with an external power supply, it says that the recommended voltage range is 7 to 12 volts. We are using 12 volt, 12 amp batteries to power the motor and we were wondering what would be the danger in connecting the arduino to this same power supply.
From what i've found so far i think the arduino only draws the current that it needs so i believe the current isn't an issue, am i right?
We also need to power the osmc, from robot power, which needs 12 Volts and once again it should only draw the current that it needs to operate right?
So that's my main concern is how do i know that it will only draw the current it needs and not too much to fry the board and are there any other solutions that we can try using.
