// HomeSpan Addressable RGBCW LED Example. Demonstrates use of two separate Accessories to control a SINGLE
|
|
// NeoPixel LED Strip. The first controls the RGB LEDs and the second controls the Warm-White and Cool-White LEDs.

// Both sets can be on at the same time.
|
|
//
|
|
// Note use of Pixel::CCT() method to convert color temperature into values for the White LEDs.
|
|
//
|
|
// Also note that HomeKit uses the Mirek scale for color temperture instead of the Kelvin scale. To convert from
|
|
// one to the other, divide into 1 million: Mirek=1.0e6/Kelvin and Kelvin=1.0e6/Mirek.
