A week ago, I asked a question about how to generate 50 LEDs and I got some very good responses. However, I need some help in some of the code. One code was written in 6.1 and I need it in 6.0 In the other code I can't change the number of LEDs from 50. Could the people who responded get in contact with me. My email i s bezayiff@physics.ucsc.edu and I was listed as Nate1. The much appreciated responders were Jeremy Braden, Jean Drolet and Nadav Chernin. I have worked through your code and will use most of it.
