RGB-fun

RGB library used to control RGB leds using PWM modulation to dim and mix the individual colors. The library uses a Color helper class to define the colors. It is possible to define colors in these ways:

  • web color notation: #FF00AA
  • Integer notation: 0 - 255
  • Floating point notation: 0.0 - 1.0

By combining red, green and blue a great amount of colors can be created. This class can accept color objects or colors in hexadecimal notation (web color notation).

Note

Effects and effectsmanager are still experimental and not documented.
