# Tip: You can also switch current layer by single click like this:

# Initialize RGBLED with pin, underglow_size, backlight_size and is_rgbw.
rgb = RGB.new(
  15,    # pin number
  0,    # size of underglow pixel
  3,   # size of backlight pixel
  false # 32bit data will be sent to a pixel if true while 24bit if false
)
# Set an effect
#  `nil` or `:off` for turning off
rgb.effect = :rainbow_mood
# Set an action when you input
#  `nil` or `:off` for turning off
# rgb.action = :thunder
# Append the feature. Will possibly be able to write `Keyboard#append(OLED.new)` in the future
kbd.append rgb

kbd.start!
