I’m looking to use the same type of leds, I have looked at the solderless tutorial, but am a little confused as to wether I need a frame grabber, or logic level shifter or even an Arduino. I’m wanting to just use the RaspberryPi 3, WS2812B leds, Kodi and Hyperion. Will this work? I just purchased an diode that adafruit says is needed, but I’m not sure about that even. There is so many different directions out there, but none of them seem to use just the parts I listed.
