Sound reactive NeoPixel LED strip installed in car

My latest and greatest project involving WAY to many led's:
--- ANY feedback here would be hugely appreciated.

--- About the project ---
I decided on installing some led strip around key points in my car and tying it all into two long strands. One for the left side, and one for the right side.

The main thing was it needed to react to sound, music specifically.

I also wanted flow, so the strip runs down the center console, under the back seats, then back up to the front along the seats by the doors then terminating under the front seat passenger's feet. (just watch the video, it'll make more sense)

I also wanted to be able to adjust several aspects of the light animation so I have 3 knobs (potentiometers) connected to my arduino that allow me to adjust variables in code.

All of this needed to run off the car's dc 12v jack so I bought a tiny converter that puts out a hefty 5v @ 2.1 amps max. The small microphone detecting sound needed constant voltage so I installed a small switch to 2x AAA batteries that sits snugly inside the control box.

I wanted it to react to sound, so I used this:

in conjunction with the mega 2650 r3 I had just received:

I had a few other components you can find at radio shack or the likes, such as potentiometers and blank breadboards for mounting stuff on.

The biggest challenge with this project was the measuring exactly how long each strip segment needed to be, and how long each section of wire between segments needed to be.

I did this carefully by using string, taping it to areas of the car, then measuring the string and finding the closest length of led's (rounded to the designated cut sections of course). Same with the wires, although these could flex so I made sure to route the string out of the way under plastic lips with a little extra so I didn't run out of wire later.

Maclin fuehr-bush, I can't reply directly to your comment, but if you're getting an error of some sort post more about it or shoot me an email (contact me through my website, in the description)

nice idea.  why not have the LEDs dim or only turn on to the beat of music instead of changiing colors?

Hi is it still possible to get the code anywhere

[mohamedkhalil]

hi this was an amazing project i had one question though did you power the whole strip from the jack or did you break off the power for each segment

This is awesome! All of the in-car music responsive LED projects I've seen so far just strobe to the music, which isn't very visually appealing in my opinion. This is the first one I really like the look of. Congrats on a project well done! I'm very interested in replicating this myself.

I am also curious as to why this code does not work on the Uno. What are we doing wrong?

can the hue adjustment be added via a pot? if so what would be the extra code please?

[dustinrichards]

How did you mount these to the interior? I'm planning on doing a project like this soon and I can't figure out a good way to mount them without drilling holes

Hello Lucas, Loved your set up. I have just started with Neopixels and Arduino. I am looking to build some thing similar to what you have created and I have no clue how to manage to hue and not strobe. Would you please share your sketch? I would really appreciate the same.

I'm so confused as too how you're powering these. Could you send a link for the converter you're using?

[CrankyCoder]

love how it looks!!!! do youhave the code you used up somewhere?

[teaiintrebatvreodata]

How mannt money you want to do this on my car!?

[mykkalwright]

what's a plug and play way to do this?

[macfuehrbush]

I can get this to work on a mega but not an uno. Is there something that should be changed?
