Project 12/21/17 Digital Dice

Here is a project that my seniors are working on, Digital Dice. We used a 74LS193 Counter and a 74LS47 Decoder and a 74LS00 NAND Gate.

How it works. The counter counts from 1-6 and displays the count on the 7 segment display. So the first count starts at 0 and goes to 1,2,3,4,5,6 at count 7 the counter resets back to a pre-set condition of 1 then counts 2,3,4,5,6 on 7 resets back to the preset of 1 then counts 2,3,4,5,6 rinse cycle and repeat.
