Hey guys, I have a project that i would like to run off of external power through the dc jack and also have a backup battery connected to the Vin in case of a power outage. Being the case that the Uno has automatic power select, do any of you know the priority order of the source inputs? i need to know this because if the Vin takes priority over the dc jack, then my backup battery would just be used until it ran out and would render itself useless. Thanks, ElectricBlood
