In
s e tu p()
there will be nothing for you to do this time,
since the program that you will be linking with the
#include
instruction will already be handling it for you.
In the main loop, the first thing to do is set the brightness:
brightness = 50;
. The highest level of brightness is set
with a value of 255; with 0, the NeoPixel remains dark.
Then the various colors are produced one after the other.
To do that, you will be assigning the
red
,
green
and
blue
variables different values.
The line
pixel.setColor(red, green, blue, brightness);
is
the decisive factor for each color. First of all, it tells the
NeoPixel that it is supposed to display a new color! In
these instructions,
setColor()
is a so-called method of
the
pixel
object. To invoke a method of an object, the
method’s name is attached to the name of the object
separated by a period.
With
delay(5 0 0);
you will make your KosmoDuino wait
half a second before adjusting the net color.
The NeoPixel
shines in
various colors
