J. Peterson / Mbed 2 deprecated CuriLightCtl

Source code for the Curilights Controller. See http://www.saccade.com/writing/projects/CuriController/ for details.

Dependencies:   FatFileSystem mbed

This is the source code for the Curilights controller. This lets you interactively control a string of Curilights. It provides a simple click-wheel user interface for changing colors, brightness and behavior. It responds to movement and lighting.
