docLamp by Doug Szumski
=======================

An RGB LED lamp project using feedback from an ADXL345 accelerometer to control the colour.

The cartesian vector from the ADXL345 is smoothed using a stack-based averaging approach and then converted to spherical polars using look up tables. This yields a stable measurement of both theta and phi, with an angular resolution of better than 0.25 degrees and a refresh rate fast enough to make the lamp highly resoponsive to the users motions. 

TODO:

* Clean up code!! 
* Fix double tap detection for mode selection (currently unreliable)
* Add schematic
