Did you know it's easy to drive a WS2812B smart RGB LED with an ATtiny?
I'm not talking about Adafruit's well-known NeoPixel library.
There's a much lighter-weight library for driving these LEDs that's perfect on memory- and flash-limited ATtiny AVRs -- or really any AVR for that matter.
All you need is the light_ws2812 library
. I'm using it with the ATtiny25 on my eeZee RGB test jig.
Adafruit gets all the attention, but this little library is small, easy to use, and works great; it deserves more press. Pass it on, k?
