Pin 7 Not High? Answered

I ran the ForLoopIteration it works but pin 8 is not going high.

It does light up but is dim.

I tested it with the blink code and pin 7 goes high. If i add an additional pin (8) with nothing connected to it pin 7 will go high. Any ideas why?

If you haven't initialized the pin as an output, you can get symptoms like you describe. Are you sure at all your outputs are declared as such in your setup function?
