Digital pins 0-3

Jim_Socks:
Pin 1 is just plain useless. It doesn't care if you set it to input or output, or try to digitalWrite to it or anything... it just does whatever it wants to do. Would be nice to be able to put it to work. "Get a job Pin 1!" lol

Did you try disabling the USART...?

When the USART is enabled it overrides normal pin functions.
