Arduino pro mini compatable

[JSkye3293]

Is it possible to make this compatible with the Arduino Pro mini or the Uno R3?
What I need is this to work with Software Serial, and to accept commands through that. (I dont have enough buttons but I do have 3 microcontrollers) I am also wondering if it was possible to use a Potentiometer as a manual brightness control?

when compiling for the mini, I get this in compiler:

Sketch uses 33,234 bytes (108%) of program storage space. Maximum is 30,720 bytes.
Global variables use 4,213 bytes (205%) of dynamic memory, leaving -2,165 bytes for local variables. Maximum is 2,048 bytes.

Overall a very cool program! I cant wait to get this to run to see what it can do. I highly respect people who take the time to write these!
