|
|
// * HomeSpan Pixel Class that provides for control of single-wire addressable RGB and RGBW LEDs, such as the WS2812 and SK6812
|
|
// * HomeSpan Dot Class that provides for control of two-wire addressable RGB LEDs, such as the APA102 and SK9822

// IMPORTANT: YOU LIKELY WILL NEED TO CHANGE THE PIN NUMBERS BELOW TO MATCH YOUR SPECIFIC ESP32/S2/C3 BOARD
