| Joe, A very handy way to connect lots of digital switches is to arrange them in a resistor ladder and connect them into an analog input. You could get up to 8 switches into one input, giving you 256 different voltage levels, in theory, but in (...) (28 years ago, 16-Jan-97, to lugnet.robotics.handyboard)
