Light Up Your Hackpack With the Adafruit NeoMatrix Library

The Adafruit NeoMatrix library is designed to make it easier for developers to program the Adafruit NeoPixel 8×8 LED Panel. The library builds on top of the Adafruit_NeoPixel and Adafruit_GFX libraries, providing abstractions that simplify the process of changing color and brightness of multiple LEDs arranged in a strip at the same time. The Adafruit_NeoMatrix Library allows for two-dimensional displays using NeoPixels and provides access to pixel positions in a grid arrangement. The library includes functions such as `colorWipe`, `fadePixel` and `crossFade` that can be used to create animations and effects on the LED display. These building blocks are all needed to create a name tag application that scrolls text, including Twitter handles, across the panel.
