Nothing special today, just a set of flows to control an [obniz board](https://obniz.com/products/obnizboard) 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](https://github.com/rozek/node-red-obniz-neopixel-matrix-test) and in the [Node-RED library](https://flows.nodered.org/flow/65a4b69a046e51bc3a1484fce5875592)
