CV-Controllable LED Lighting

I wanted to add some LED lighting to my Eurorack, so I added some LED strips with CV inputs for hue and brightness.

In my case, I used 150 LEDs total with 1 data input from the Teensy 3.6, and used a 5V 3A power supply to power the LEDs.

The Teensy has a separate low amp power supply, and the ground from Teensy is connected to the ground from the 5V 3A power supply. Additionally, a 1000 uF 16V cap across the 5V 3A supply adds some protection.

The Teensy code uses the FastLED library. 

The code and schematic are available here:
