Arduino AreGeeBee color mixer

I recently got an Arduino microcontroller to tinker with and just wrapped up my first project, which I am calling the AreGeeBee color mixer. It allows a user to adjust the color output of a LED by changing the color values as displayed on the screen. A knob is rotated to select which color to change, and then two buttons are used for increasing or decreasing the color’s value.

Check it out in action:

The source code is available here for anyone who is curious how it works or wants to replicate it.
