Arduino Library

The Soldered WS2812B Grid library drives this board. Include WS2812Grid-SOLDERED.h and create a WS2812Grid object with the pin wired to DIN. begin() starts it with every pixel off, setPixel() colours one LED by its (x, y) position and show() sends the colours to the grid.

(0, 0) is the top-left LED, where the data enters. x grows to the right and y downward, so you never deal with the serpentine order the LEDs are wired in. For several chained grids, pass the panel's full width and height (multiples of 8) to the constructor and the same coordinates run across all of them.

The library builds on a bundled copy of the Soldered WS2812 library, itself based on the Adafruit NeoPixel driver, so show(), clear(), setBrightness() and Color() come from there.
