Each square on the standard chessboard is assigned a decimal number and equipped with a sensor to detect the presence of a chess piece. A total of $64$ sensors are distributed across the $8$x$8$ grid of squares on the board, interfacing signals into the digital electronics system. The system processes input signals from each sensor on the square, converting them into a $7-$bit binary output number that corresponds to the specific chess piece located at the respective square, with an equivalent decimal number. For instance, if the system outputs the $7-$bit binary code $\text{'}0000101,\text{'}$ it indicates that the chess piece is located at the square with a decimal number $5.$
