With my Jarduino setup I've got 7 channels with the moon lights included. Each channel is separately controlled and only one colour comes on at a time. But that's a one time set up and once dialed in never touched again. One feature I want to incorporate but don't have yet is a acclimation feature. You get new corals in, hit a button and the fixture dims to say 60% of your regular day to day functions, and over the course of say a week or 2 maybe, it ramps back to the original settings. Perhaps an increase of a few percent per day or something.
For the techy photo guys they may want a save function for say 10K, 15K or 20K, so that if they're going to take pics but their cameras suck at certain K ratings they just hit a pre-set button that they made when they first set it up, and voila perfect light mix for pic taking.
That's all I can think of right now and maybe some of that is already in there but didn't follow some of the original description
Looks awesome though. Can't wait to see it.
