``ws2812`` - Neopixel LEDs
The ``ws2812`` module controls LEDs of the WS2812 type. Just as the ``leds`` module, it exposes a function :py:func:`ws2812.set_all`, which works a similar fashion.
.. py:function:: set_all(pin, colors)
Set multiple of the LEDs to RGB values.
Filling starts at the LED connected to the specified gpio pin.
:param int pin: ID of the pin to use for sending the data.
:param colors: List of RGB triplets.
.. code-block:: python
import color, utime, ws2812, gpio
i = 0
while True:
col1 = color.from_hsv(i % 360, 1.0, 0.1)
col2 = color.from_hsv((i + 20) % 360, 1.0, 0.1)
col3 = color.from_hsv((i + 40) % 360, 1.0, 0.1)
ws2812.set_all(gpio.WRISTBAND_2, [col1, col2, col3])
i += 1
