I came around a little problem while working on my project. I tried to read a 4x3 matrix but i can't seem to get it working with a analog pin. Does anyone have the code and solution to this problem would be nice. Kind regards Wouter

Hi,
Change from a UNO to a MEGA, more I/O and you can then use the 3x4 digital keyboard.
