Help in trying to build microcontroller powered Chess Board

  1. Sep 30, 2014 #1
    Hello all, as the title states I'm trying to build an arduino powered chess board. The chess pieces will have magnets on the bottom and each square of the board will be equipped with a reed switch for detecting the presence of the magnetic field produced by the magnet. I recently tried this out and the neodymium magnets I bought were so powerful the field cut into adjacent squares' reed switches and gave false signals.

    Does any know of a less powerful type of magnet that I can use? If you think this would be more of an application of RFID tags (an application that I've seen on the interwebs quite a lot) what sort of resources do you recommend so I may learn how to apply it?
