The triangularWave function has a period of 256 and provides for a smooth ramp-up and ramp-down.

  int b = triangularWave(t_repeating / 10);

The next function takes three arguments: The red, green, and blue components of the color we desire. We are mixing only red and blue, setting green to zero.

  SpinWheel.setLargeLEDsUniform(b, 0, b);
