We’ve already seen that it is possible to drive thousands of WS2812B NeoPixels with a lowly Arduino using careful bit-banging. But what if we could bang out 8 bits at a time rather than sending them single file? Could it be possible to drive 8 times as many strings (or get 8 times the refresh rate) from our Arduino by processing bits in parallel? It would be like having a tiny pipelined GPU render engine inside our Arduino!
