Re: PLC Program for Lighted Arches
Welcome to DIYC, the hobby that never ends.
When I first started looking into this hobby, I too was going to use a PLC, but found it to be way to restrictive. The controllers you find here in the WIKI work much better, are cheaper to build, and are a lot easier to communicate with. A lot of us program our songs with 50ms changes in our sequencing. Thats a lot of data for the PLC to handle. Also if you use something like the REN series controllers, you have the ability to dim your channels. When building arches, I have found this to look a lot better. The arches I built last year are all LED, with 8 segments per arch. I used 10 foot piece of 3/4 PVC EMT. The sequencing I found that works the best is 100 ms on with a 200ms fade to off. That way it looks like a tail on the arch.
Everyone does things different here, and that is the fun part. It always keeps your mind thinking about how to improve your own display.
Good luck, and have fun with this. Oh and one last thing, on this forum, there is no such thing as a dumb question. So feel free to ask.
