I'd like to make a chess-board with the ability to detect the position of each piece.
The solution that occurs to me would be to put an RFID reader under each square and put RFID tags on the bottoms of each piece.
However, apart from the obvious cost (64 readers!) I'm concerned that:
- Maybe RFID readers are too large for the squares of an ordinary chessboard
- RFID reader range is too large, so a reader might pick up pieces on neighbouring squares
- How the hell would I connect 64 readers anyway? Could an Arduino handle it?
Is this just stupid? And is there a better technology to use for this kind of application?
If RFIDs are basically a sane solution, what are the issues/suggestions? E.g. which RFID readers should I go for? (Based on size, energy, convenience for this application). What boards would let me handle this number of them?
