Show us how you have the project wired in a schematic.
I cant take a picture at this time, as I do not have the board with me(I also can not try it with only pin 9) but here is a picture That is not photoshopped in any way of the same exact design as I used. I just unplug the wires that I do not want to detect as HIGH and plug them in when I do want them to.
I will try this. Thank you for showing me this. I figured that a pullup would not be needed in this case, but you are probably correct, I will try this when I get home.
