garyd9: The supply voltage is all in parallel for the fans. You can just use the next one to run you LED strip without much problem.
So, I started playing with this the other day and the CLI was super confusing at first, but I finally got the hang of it. Changing it manually was still a PITA so I wrote a quick app in Processing today to make it a little easier. It's just a direct interface to the settings, but hopefully, I can grow it up over the next few weeks.
It's up on my GitHub here: https://github.com/ILAMtitan/HD120HostController
To use it, you'll need the latest version of Processing: https://processing.org/
and Control P5: http://www.sojamo.de/libraries/controlP5/
Start processing once, and it will create a "Processing" directory in your documents. Just drop the controlp5 library folder inside the "libraries" folder there to install it. After that, just open the PDE and hit the triangle. If you're happy with it, you can also export an exe so it's easier to run.
Once you get it open, just select the com port of the Arduino, the fan you want to configure, and the mode you want. Once you get the settings tweaked, hit send to update it. If you change the fan number, the rest of the settings will remain, so you can get them all the same if you like. Once you like it, just hit SetDefault to save it all to the controller.
A lot of the ranges for the sliders were kinda guesses, so any feedback on better ones would be appreciated. Actually, any feedback at all would be good.
Still on my todo list:
Tweak slider ranges
Optimize interface
Implement the Global Settings (Once I figure out how they work)
Clean up code
Document (notice this is last, so no guarantees)
