Convert ADAlight Digital RGB LED code for Analog LED

[XZ3R0]

I'm looking to convert this code  for the ADAlight Project Pack which is made for a digital rgb led strip into a 1 pixel resolution analog strip.

I'm new to microcontrollers/arduino, but I understand a lot of the code just not comfortable with serial reading and writing yet. How might I go about reducing this project to output to a single analog 'pixel' instead of the array of digital leds?

Excuse my ignorance but what is a '1 pixel resolution analogue strip'? Maybe a link to the product?

Sorry if that was confusing, when i say 1 pixel I'm referencing the project which is meant to be used with a digital/addressable rgb led strip where each led is a pixel. I am trying to use an analog strip which effectively reduces the project down to only 1 pixel of resolution. (don't ask why i want this, lol)
