Neopixel Matrix Test with Obniz Boards

Nothing special today, just a set of flows to control an obniz board with an attached Neopixel 16x16 RGB matrix - although they may easily be adapted to other geometries of chained WS2812 RGB LEDs (but only up to a length of 85 LEDs because of restrictions in the obniz board)

While the idea behind the obniz board has its benefits, the quality of software and documentation is...not really optimal - these flows may therefore perhaps help newcomers to work with the board and attached WS2812 strings.

May be found on GitHub and in the Node-RED library
