Please help me, no arduino sketch is working for me. Maybe you can send me a checked and working sketch for arduino. I have already tried everyone, from the official website of the hyperion, and with fast led and nothing. Even from the tutorial that is here. And the only thing I get is a led test at the beginning. In the arduino is ok everything because the TX flashes all the time as I have set on the videograbber. My diodes are WS2812B. Thank you!!!!
