Flip red and blue channels in animation driver to match real arrow wiring.

Add two animations:

PinwheelAnimation
MorseCodeAnimation

8. By David Sunderland on 2011-08-21

Several changes in this release:

pwm.cpp:
* fix bug in actionStep which causes slower PWM cycle by extending highest level (255) to the end of the PWM cycle

bfa/bfa.pde:
* add .pde file for building in Arduino IDE

joystick.*, main.cpp, animation_driver.*:
* add controller for selecting animation mode
* make main mode of operation randomly switch between animations periodically

animation_driver.h:
* reduce the number of pixels from 10 to 8

animation.*:
* add ColorCycleAnimation, which cycles through primary colors
* fix FadeAnimation to fade incrementally through primary colors
* add WaveAnimation, which sends a pulse from the tail to the head of the arrow
* add RandomAnimation, which randomly changes the color of pixels

7. By David Sunderland on 2011-08-15

Add new interface for running animations. For now, just two basic animations (arrow blinks, and arrow cycles red-green-blue), with a main loop that switches between them every 15 seconds.

removed:
  effects.cpp
  effects.h
added:
  animation.cpp
  animation.h
  animation_driver.cpp
  animation_driver.h
modified:
  main.cpp
  pwm.cpp

6. By David Sunderland on 2011-08-13

Fix performance problems with PWM interrupt code by unrolling loop and removing branches. Add framework for defining animation sequences, with a base color cycle (red, green, blue) animation.

5. By David Sunderland on 2011-07-27

PWM module is now manually tested on ATmega2560. Added simple main program for demonstrating PWM; it is clear that our software PWM is currently quite inferior (in terms of frequency--very noticable flicker) to the hardware PWM, and slow to boot. But, it works.

added:
  fade.h
  main.cpp
modified:
  pwm.cpp
  pwm.h

4. By David Sunderland on 2011-07-20

Initial checkin: factor PWM logic from Groovix code into a separate module. Add support for the pin mappings on Arduino Mega 2560 (though it should probably work for any model).

added:
  pwm.cpp
  pwm.h
