I'm not sure what's going on but something in my system is damaging my Arduinos. 5v phone charger power supply runs them which should be fine... But the one works fine and the other keeps messing up and reading high voltage with no input. Plus I'm confused with the outputs .... 5 plus output ports and 1 gnd port. I guess gnd can just be bridged but still. Arduinos are cool but tough as butter on the sun...
I can't speak for anyone else obviously, but I have no clue what that statement is getting at. (Is there an implied question?)
Nvm....all my problems were due to a too low voltage input into Arduino....So many problems
