I seem to be having an issue with the digital ins not working on pins 1-7. I know pins 1 and 2 and used for rx tx, but for some reason I cannot get 3-7 to register any input. Pins 8 and up work just fine. I tested them with basic 5 volts going in, and nothing happening. The moment I got to pin 8 it registered just fine.
Any ideas come to mind as to what it might be?
I am using a SB-Freeduino v2.2, with a 328p chip. I currently use digital in 8, servos on pins 9,10, and temp sensors on analog inputs 1-4.
