I'm running using a 3.5V input (because I have to power the arduino from a battery) and for some reason my Arduino won't recognize the 3.5V it as a HIGH input. Really not sure what is wrong here. Any help?

Arduino minimum high threshold?

Oh dear God....

Sorry for wasting your time gents. I've been bouncing back and forth between problems and got so lost I did this. Thank you for your help
