enter code hererandom W0 enter code hereW0=W0//10 enter code hereif W0 = 0 then let pinsb = %01110111 endif enter code hereif W0 = 1 then let pinsb = %00010100 endif enter code hereif W0 = 2 then let pinsb = %10110011 endif enter code hereif W0 = 3 then let pinsb = %10110110 endif enter code hereif W0 = 4 then let pinsb = %11010100 endif enter code hereif W0 = 5 then let pinsb = %11100110 endif enter code hereif W0 = 6 then let pinsb = %11100111 endif enter code hereif W0 = 7 then let pinsb = %00110100 endif center code hereif W0 = 8 then let pinsb = %11110111 endif
enter code hereif W0 = 9 then let pinsb = %11110100 endif
