Ha, no problem
I thought there was something I didn't know going on. I swapped in sink's code, and combined my two WW strings and CW strings so that they can run through the same 2 PWMs. Now I have what I needed: too much light, haha! So, I'm using the analog control to dim the CW as much as possible, and I'll be tinkering with light levels over the next few weeks. I also set up the CW to run as moonlights at night - that's kind of neat: the color is much more agreeable than the royal blues I was using before. I'm just hoping that it doesn't cause too much algae trouble, I'll keep it low and see how it goes.
Now, to see how I can use this bad boy to control my CO2 - I'm SO sick of my mechanical timers getting jammed. Do you know of anyone who has a code/setup for this?
