Easy Install NeoPixel Christmas Light System

// 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
//

// For Esp8266, the Pin is omitted and it uses GPIO3 due to DMA hardware use.  
// There are other Esp8266 alternative methods that provide more pin options, but also have
// other side effects.

// NeoEsp8266Uart800KbpsMethod uses GPI02 instead

// You can also use one of these for Esp8266, 
// each having their own restrictions
//
// These two are the same as above as the DMA method is the default
// NOTE: These will ignore the PIN and use GPI03 pin
