To Do

  1. Modify the “simple sketch” so that it displays each of the internal LEDs in
    3 different brightness levels. So instead of just dark and bright, assign
    a value to bright, brighter, and brightest. (Hint: for common anode RGBs,
    brightest would have the value 255; bright and brigher would have
    intermediate values.)

  2. Modify the “rainbow” example to use a lower value of tilt and show that
    the red light is, as expected, more suppressed as a result.

  3. Modify the “rainbow” example so that it goes through the spectrum in the
    opposite direction, i.e., from red to yellow to green to blue to purple.
