// MATRIX DECLARATION:
// Parameter 1 = width of NeoPixel matrix
// Parameter 2 = height of matrix
// Parameter 3 = pin number (most are valid)
// Parameter 4 = matrix layout flags, add together as needed:
// NEO_MATRIX_TOP, NEO_MATRIX_BOTTOM, NEO_MATRIX_LEFT, NEO_MATRIX_RIGHT:
// Position of the FIRST LED in the matrix; pick two, e.g.
// NEO_MATRIX_TOP + NEO_MATRIX_LEFT for the top-left corner.
// NEO_MATRIX_ROWS, NEO_MATRIX_COLUMNS: LEDs are arranged in horizontal
// rows or in vertical columns, respectively; pick one or the other.
// NEO_MATRIX_PROGRESSIVE, NEO_MATRIX_ZIGZAG: all rows/columns proceed
// in the same order, or alternate lines reverse direction; pick one.
// See example below for these values in action.
// Parameter 5 = pixel type flags, add together as needed:
// NEO_KHZ800
// NEO_KHZ400
// NEO_GRB
// NEO_RGB
// Example for NeoPixel Shield.
// as a 5x8 tall matrix, with the USB port positioned at the top of the
// Arduino. When held that way, the first pixel is at the top right, and
// lines are arranged in columns, progressive order.
// 800 KHz (v2) pixels that expect GRB colour data.

La primera parte incluye las 3 bibliotecas (NEOPIXEL, NEOMATRIX y GFX).
Luego, volveremos a determinar un pin de salida. Es el mismo principio que el del capítulo anterior.

800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
Pixels are wired for GRB bitstream (most NeoPixel products)
Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
