I'd go for the casino idea... love Vegas!

You are just way beyond my understanding!

Really, though, you are right that no one is going to notice any sequencing as it is happening. I could just use the Random command to end up with the same thing. I just don't like that on start up it will always start with the same thing.

Let me try and describe my project better.

There are 16 LEDs that will always be on EXCEPT for one that will randomly "blink" off then come back on. Repeat with another random LED and go on this way forever.

Using the 74HCT154 multiplexer makes the job of holding the LED's on a blinking just one at a time easy and it requires 5 inputs in different combinations of high and low to do that. Sounds simple enough at this point.

So using RANDOM to come up with 5 combinations of "0" and "1" in itself is simple using > and < to set the pin. The circuit "should" run away happily forever with not much coding at all except that on each start up it starts the same way and would be noticable until some point where the viewer lost track. Sort of like Pi. We can all remember the first few digits then we just sort of don't pay attention after that.

To get away from this problem I thought I should somehow seed the generator with an outside event. Not because it totally can't work any other way, but because it is neat to come up with a solution that my limited knowledge can carry out.

I've been reading the manual for the PicBasic and trying to understand "Free running" 555 timers and how I could make the two work together under PicBasic and some type of PIC controller. Right now it is all somewhat above me.

Thanks.
