i in the progress of modifying the neopixels buttoncycler exemple.
but how can i make each "case" run infinite times until i press the button agien?
now it just run each case once then stop.
i*m thinking especially on
case 4
case 5
case 6
// This is a demonstration on how to use an input device to trigger changes on your neo pixels.
// You should wire a momentary push button to connect from ground to a digital IO pin. When you
// press the button it will change to a new pixel animation. Note that you need to press the
// button once to start the first animation!
