hello, i tried to follow this tutorial: http://arduino.cc/en/Tutorial/RowColumnScanning
but the whole matrix is always lit and only one row and one column does not light.
for the x and y coordinate i didnt use the analog input but i change them programmatically with a delay(500); http://pastebin.com/L7D8YxXJ
i am pretty sure i did the wiring correct. what else could i have done wrong?
here is a photo:
