Yes, but the very cheap versions of usb-serial adapters have all kinds of problems. I personally use only adapters that I know have genuine FTDI chips on them. I resell the Adafruit FTDI Friend adapter. More expensive, but no problems, either.

I’d love to see your project when you are done!
No, the Lumazoid cannot control more than 3 meters with a unique pattern. You can run multiple strips in parallel showing the same pattern, but 30-40m would require an incredible amount of current.
I just quickly added support for Leonardo on a branch that you can try. I tested this and it works.

Oh, I’m sorry about that. This is a very old product and only works with AVR based Arduino boards like the Duemilanove and the Uno. Back when I made this product in 2009, there were no Arduino boards that were not based on an AVR microcontroller. I need to make this clear in the documentation, and I think I owe you a refund since this constraint was not clear.
I assume you installed the EZ-Expander library. What kind of Arduino are you using?
Can you post your code?

Hmm. That should work for you. The INPUT and OUTPUT pads on the board are electrically connected to the RCA jacks. Did you connect the grounds, though? The outer part of an RCA plug is the ground connection, so the ground connections from your input and output (LCD monitor) need to be connected to a ground connection on the Arduino. Maybe that’s the problem?
Hey kreiff,
I’m not really an expert on guitar pedals, but I have read that popping sounds can be eliminated by connecting a large resistor (like 1M) between the audio signal and ground. This gives the circuit a path to bleed off the voltage when you turn it on/off.

Google and you can find some references to this solution. It won’t hurt to connect a large resistor to ground.

Yes, you can absolutely connect another LED strip to the same connections and the same visualization will be displayed on each strip. As long as you provide enough current for all the LEDs, this works fine.
I don’t have any more visualizations, but I’m interested in which other LED controllers you are referring to. As far as I know, the Lumazoid is far and away the best music-reactive LED controller. I know of only one other, and it is far more expensive.
I think you are close. Just keep experimenting. Yes, the increment of 3 bytes for addresses is due to packing two 12-bit samples into 3 bytes. It makes things more complicated, though.
