im still trying to set up your first version of the project, and i cant get it working, if you could look at the posts on the last page and help me figure out whats not good, i'd be very gratful 
it's just that i have this huge buttons pad sitting on my desk, and it doesent seem to be working, and wires are running everywhere, and there bread boards to the waazoo, as soon as i get this running i can stick it in a nice case, and furthur program from there.
the code you gave me is so far just making rows of the same color light up except for one row which isint lighting up, and 2 rows of which only work when i press a button, and the last row, is on, but when i disconnect the button ground, then the buttons freak out for bout a second, then they all turn on... wierd, if you could put up a schematic just for how you hooked up the buttons, i think i could get this working.
thnks
