There are ten NeoPixel LEDs and two buttons on your Circuit Playground Bluefruit. This example lights up half of the NeoPixel LEDs for each button when pressed.

Try pressing button A to see the left half of the LEDs light up red, and button B to see the right half of the LEDs light up green.

# (r, g, b) represents red, green, and blue. Each value has a range of 0-255, where 0 is off and
# 255 is max intensity. You can update these values to change the colors. For example, (0, 255, 0)
# would be max green. You can combine numbers within the range to make other colors such as
# (255, 0, 180) being pink. Try it out!
