I may need to do that. After reading this it also gave me the idea that I can put everything on a breadboard and put an LED on all the outputs and see what lights up when the program runs. If I see the 5 LEDs changing their on/off states I will know the proper combinations are being sent to the multiplexer inputs.

Before all that, though, I think I will make one LED blink then run the thing around town showing it off! :-)
