That lead me to a tutorial from Hacktronics. I felt that the article was helpful, but I was left to my own devices to write the code other than a big hint as to how to get Arduino to display numbers. Some trial & error came in to play here as I discovered that the documentation for my displays, aside from being hard to read, was completely incorrect with the pinout data. Also, I realized the difference between a LEDs with a common cathode vs. a common anode: the digitalWrite values (HIGH & LOW) are opposite for which ones you are using. With my common cathode LEDs, on is HIGH & off is LOW. (Also, here is an explanation of the difference between a common anode vs. common cathode.)
