Parallel Bit-Banging Eight NeoPixel Strips from One #Arduino
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!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
