Help Planning Multi-Channel LED Controller

[herring_fish]

I need help with early planning of a multi-channel LED controller. I don't yet know what I don't know yet. I will update this list as I come up with more question as well in subsequent posts.

Background Exeriance:
Perhaps, I am intermediate level "œhobbyist only" Arduino programmer, having had one good sized project. I built a 2 axis robot to feed plankton cultures which feed my tank. I used two stepper driver boards and a color LCD. I also used an 8 channel 110V AC relay board to turn on and off the feed pumps.

I have also built a small application that feed files to another program so I have some exposure to a basic user interface.

Without knowing much about LED controllers, I guess that an Arduino can handle the job. Do I need some add on boards besides the relay board and a YiFi? Can I use the same relay board that I am familiar with?
Do you simply go from the PWM outputs to the relay and then you plug the driver into the AC outlet that the relay controls or do you use a different route?

0-100 is only possible with PWM driver. Look at LDD thread I started on this forum.
