around 50 led's in the 3 strips, (18, 18, 14) and 12 in the hd120 for the fan.

I.e. if they can be separate could control all 4 strips to have different things on them.
(Or filament bay as one thing, the 2 strips in the printer section another thing and the fan a 3rd different thing.)
I know i do still have 4 potential outputs on the arduino nano that using that i can run the lights data outputs from.
You can either run each fan/strip on separate outputs (Not efficient code-wise) or you can daisy-chain them and address them in series. That is, Fan 1 is LEDs 0-11, fan two is 12-23, and so on. The fourth pin on the fans' LED connection is the data coming from the far end of the LEDs on the fan and to be sent to the next fan.
