How I connect lights to my modular synth

I've been getting a lot of questions about how I sync my lights with my modular synth, so I created a short video to share how I built them, along with instructions and the source code.

I’m NOT an expert in electronics. I’m a hacker/tinkerer at best, but these lights have been working well for me in my setup. I’ve lugged them around with me to gigs, and different locations, and they’ve been pretty sturdy and reliable so far. If you have questions, or suggestions on how to improve please post it in the comments.

Everything is completely open sourced, but if you’d like to support, check out my online store where you can get my vinyl, and pretty cool t-shirts: https://iiitaiii.bigcartel.com/

Features:

CV gate signal triggers light to go on
You can control how long the fade is (from immediate/no fade, to infinite)

there are 2 ways to control the color:
1) with a potentiometer knob
2) with voltage receiving 0-5v
(to select between the 2 options, there is a switch selector)

Parts:

Arduino (Uno or equvilant)
LED Strip - Analog (I used 2 meters)
3 Mosfet 30v/60a 2 Potentiometers (10k)
2 1/4" mono audio jacks
1 toggle switch power supply (12v 5A recommended)
(for a 2 meter strip 1A should be enough)
