description
Intel Galileo acts as a chess client: read the chess figures position (NFC tags) and send the positions into the cloud. An Intel Edison reads the positions, calculates the best move (with Stockfish) and write the result back to the cloud. The Intel Galileo reads the bestmove result and shows it.
