In setup() there will be nothing for you to do this time,
since the program that you will be linking with the
instruction will already be handling it for you.
#include
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
variables different values.
blue
The line
pixel.setColor(red, green, blue, brightness);
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()
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(500); you will make your KosmoDuino wait
half a second before adjusting the net color.
