The signal is connected to an output pin and given as parameter (in the example pin 0). The chip to decode the protocol - built into the NeoPixel ring - is WS2812. They are also available in different sizes (more or less LEDs) and different shapes (e.g. band). You have to provide the total number of LEDs as parameter. |
