FRC 7902 WS2812 Controller Project

This program allows the RIO to control two WS2812 LED strips simultaneously using a Raspberry Pi Pico.

A command is sent in this order (do not have any spaces in the input):

0,1,2,3,4,5

0: Strip to Control (from 0 - 2)

1: Brightness (from 0 - 255)

2: Mode (from 1 - 6)

3: R (Red value)

4: G (Green value)

5: B (Blue value)

Modes:

1: Static Lights

2: Strobing Lights

3: RGB Colourwave

4: Pulsing Lights

5: Pattern Lights (I don't know what to properly call this one)
