+// 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
