Lights

Let’s explore further.

We can do all sorts of crazy things by adding to the while loop.

Here we will tell the circuit to turn on some colorful lights.

from adafruit_circuitplayground.express import cpx

cpx.pixels.brightness = 0.3
cpx.pixels.fill((0, 0, 0))

while True:

    # notice how these lines are similar
    cpx.pixels[0] = (255, 0, 0)
    cpx.pixels[1] = (255, 127, 0)
    cpx.pixels[2] = (0, 255, 0)
    cpx.pixels[3] = (0, 255, 127)
    cpx.pixels[4] = (75, 0, 130)
    cpx.pixels[5] = (60, 0, 255)
    cpx.pixels[6] = (255, 255, 255)
    cpx.pixels[7] = (0, 100, 0)
    cpx.pixels[8] = (100, 0, 0)
    cpx.pixels[9] = (0, 0, 100)

    # the [] with a number determines which light to turn on
    # and the numbers in () deterine the color!
    # It says how much (red, green, blue) we want.
    # Try changing the numbers!

    # this line turns on the lights!
    cpx.pixels.show()
