LED Dice (multiple)

Other Hardware LEDs and Multiplexing
1

I want to work on a more advanced project and want to expand on the led dice project (six LED's randomly light up to represent a number). I was wondering if you think that this project would be possible.

Have two random number generators output to two sets of three LED's (I do not want to use the 7 segment displays) and then have one of two LED's light up to show which side had the higher number. So essentially it would act like rock-paper-scissors.

Any ideas or suggestions are appreciated. Is this even possible?

Yes perfectly possible.

Have two random number generators output to two sets of three LED's

Why not have two proper patterned dice ( using 7 LEDs per dice ).

Use two shift registers for getting the outputs and use an array for a look up table for the pattern to display.

You only need 4 outputs for a 7LED dice face because opposite lights are always on together:

Face:
a b
cde
f g

One:
. .
.o.
. .

Two:
o .
...
. o

Three:
o .
.o.
. o

Four:
o o
...
o o

Five
o o
.o.
o o

Six:
o o
o.o
o o

So a=g, b=f, and c=e.

Also it is fairly simple logic to convert numbers to a dice face:

In|abcd
--+----
 1|0001
 2|1000
 3|1001
 4|1100
 5|1101
 6|1110
