Week 2 : LED controller

Assignment:Lighting controller

Make a device to control a light. Use an RGB LED as a stand-in for a larger lamp in class. Your device should support the following actions:

  • A control to turn the light on and off. When it turns on, it should retain the relative red, green, and blue brightness levels from when it was last turned on.
  • The ability to fade each color channel (red, green, and blue) from off to full brightness
    • Fade level should be maintained when you release the fade controller
    • Fade should be interrruptable by other controllers, e.g. on/off or another fade controller
  • The ability to fade the overall brightness of the light
