Hi
I've created the following circuit on a breadboard in class, and we need to modify it to display hours and minutes as well as seconds. I know I will need 6 x 7 segment displays, and that I want the first couple to reset after 23, the second and third couples to reset after 59. As it is, it resets after 99. How do I get it to do what I want? It's using a 74LS163 up counter, a 7447 BCD decoder and a 555 timer along with 7400 NAND gate, 7432 OR gate at 7404 Inverter.
Thanks
