In another post I made a couple weeks ago, I was told not to connect AREF when the whole circuit uses the same 5v power. I am looking at this project for my camera: DIY Intervelometer scroll down to part 4, there's a schematic. It shows AREF connected to 5v, for thermistor and photoresistor. Is that going to be a problem and that I can ignore the offending AREF pin?
Actually is there any time that I need to attach voltage to AREF pin at all?
