Adafruit Neopixel Button Cycler Sample Adapted....
Posted: Mon Nov 16, 2015 3:04 pmThis will use the Flash button to select the animation from the default Sample Sketch but also host an AP with a web page to select from some of the animations pre loaded with the library.
This includes some other web pages in the sketch I have left in to be reused...along with lots of extra declarations.....still loads of resources so re-use.....

// This is a demonstration on how to use an input device & webpage to trigger changes on your neo pixels.
// You should wire a momentary push button to connect from ground to a digital IO pin(use the flash button).
// When you press the button it will change to a new pixel animation. Note that you need to press the
// button once or trigger from webpage to start the first animation!
