Your sketch looks OK to me.  It looks pretty familiar as well - but that's how I learned all of my programming.

Don,

I think I almost follow your wiring and code.  

What's the little square thing on the breadboard to the left of each display, though?  Seems like it's tweaking the power for the LCD?

It's the potentiometer that is used to adjust the contrast voltage (pin 3).  

It's the the kind of potentiometer that is designed to be soldered onto a PC board.

Awesome.  Thanks!  Pieces are coming together.   I may just be able to build that new derby track for the scouts after all.
