If the button is interrupt serviced, then almost any button press will=20
generate a random number with just a simple counter (not too many people=20
I know can repeatably stop a counter with a 4 MHz clock).  Just read the=20
bottom 3 bits of the counter, subtract 1 if greater than 6 or less than=20
1, and you're there.  This DOES introduce a less than totally uniform=20
distribution if you need true randomness--then you must do a little more=20
work and implement a mod-6 counter.
