Hi @kfrajer,

This question is actually a part of this project: [A universal ambilight](https://discourse.processing.org/t/a-universal-ambilight/1962)

To sum up, I’m getting my TV feed through a camera set on a RPi using processing. Based on that feed, I compute the color of my LEDs.

Now I need to send those LED colors (229 colors) to an arduino plug into my LED strip to light them up!

I want to do that using bluetooth but since I have trouble with it I first want to proof test everything with a simple USB connection between the RPi and the arduino.

I still have the blueduino and an arduino micro but I don’t have a long enough USB cable to connect them to the RPi…

Since I want to proof test the system, I’m not sure an arduino simulator would work in my case because I need the output to actually light up the LEDs.

Also I should receive my new arduino and a bluetooth 2.0 arduino module by Friday so I’ll have the whole weekend to try it out 🙂

Thanks anyway!
