// NeoPixelTest

// This example will cycle between showing four pixels as Red, Green, Blue, White
|
|
// and then showing those pixels as Black.
|
|
//
|
|
// Included but commented out are examples of configuring a NeoPixelBus for
|
|
// different color order including an extra white channel, different data speeds, and
|
|
// for Esp8266 different methods to send the data.
|
|
// NOTE: You will need to make sure to pick the one for your platform
|
|
//
|
|
//
|
|
// There is serial output of the current state so you can confirm and follow along
|
