Hi
Have done similar thing with ST62x
One port reads 4040 counter outputs(lower 5 bits). This is random
number in minutes and seconds. Three spare switches TV, lounge light
and kitchen. 4 more ports drive front rooms and barthroom.
Only one of the 4 lights is on at any particular time. The
tv+lounge+kitchen is always on. After 6 a random number is taken and
represents the minutes to wait before any lights get switched. The
seconds time is the delay between light off untill next light on
Oh yes, which light will get switched on ? The bits of the 4040
decides that. There are more features but i'm wasting bandwidth.
mail me.
Regards
Cassie
