//  neopixel_strip_sw
//
//  Example of neopixel routine changing based on switch
//  Setup:
//       - Wire neoPixel strip on pin 6
//       - Wire switch between pin 5 and Gnd
//------------------------------------------------------

// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
//   NEO_RGB     Pixels are wired for RGB bitstream
//   NEO_GRB     Pixels are wired for GRB bitstream
//   NEO_KHZ400  400 KHz bitstream (e.g. FLORA pixels)
//   NEO_KHZ800  800 KHz bitstream (e.g. High Density LED strip)
