Firefly, Grasshopper - BTF WS2812B LED Strip

Hello to anyone that can help, @AndyPayne you might have a solution for this or can direct me,

I am attempting to use Grasshopper and Firefly to connect a microphone input to an LED strip output via Arduino Uno. I am able to get the Microphone to pick up audio, that isn’t an issue, but where I am struggling is getting the BTF WS2812B light strip to illuminate at all, let alone respond to audio that has been read by the program.

I’m pretty new to this world of computing, so I am likely doing something incorrect but do you happen to have any resources or basic grasshopper scripts that will get me on my way? I’ve done quite a bit of research and as of yet have not been able to locate any documentation that speaks specifically to individually addressable LED strips inside Firefly. (I’ve found lots about single LED bulbs).

I appreciate any help you can provide!

I’d recommend trying to get the LED strip working with an Arduino first bed we start with Firefly. This is only because I don’t have a default Arduino sketch for this type of LED strip. Have you tried following this tutorial: https://howtomechatronics.com/tutorials/arduino/how-to-control-ws2812b-individually-addressable-leds-using-arduino/. I’d start there and see if you can at least get the Arduino talking to it and once you have that we can make a custom sketch to make Firefly work with it.

Hey Andy!

Thanks for getting back to me on this so quickly. I’ll try the resource that you shared and see what I can do.

Thanks again!
