Well, dog gone it, I wasn't able to do things how I wanted. Turns out these HLG drivers cannot dim to zero, and if I wanted to use them I'd have to relay the power to the driver to turn them off. Needless to say I'm a bit disappointed, but I have only myself to blame for either not remembering that, or not doing enough research on them in the first place. The dimmest they get is almost 50%
If I knew a bit more about arduino programming language I think I could do it, but I'm not there. I have an extra Arduino Mega board, I'll probably keep the drivers and play with it over the next year or two and see if I can get it working, but for now I scrapped the idea, removed them from the system and built another LDD board for the XML LED's. They're going to be severely underpowered but I still think I'm going to have a lot of light. A total of 156 Cree and Exotic LED's.
Everything works fine now, but I am going to tweek some of the proto boards over the summer and swap them in for what there's now, so no real down time for the lighting.
Hopefully get some pics up of the finished product here in the next few days.
