(...) Since the analog inputs read voltage levels, you should be able to just plug in any switch or 5-0volt input directly. To read the values, use the analog command, and in theory you should only get two possible values, 255 for +5volts, and 0 for (...) (25 years ago, 27-Sep-99, to lugnet.robotics.handyboard)
