tens,

I am currently working on the same type of project, on a slightly larger
scale.  I have 10 input switches (for 10 people).  I also wanted to have
10 output lights.  As you know, a PIC's i/o pins do not suit this.  I
had to do a little multiplexing... plus, I have a buzzer sound as well.
If you are interested in exchanging ideas, I would look forward to it...
