@skatun , Hmm, two things I can think of:

  1. Are you sure you have the latest version of the FastLED library installed in your Arduino environment? Check Library Manager and see which version of FastLED you have (update to the latest).

  2. You’re using the code directly from burhAutomation’s Github repository, correct? There may have been some breaking changes, I haven’t pulled the latest from it since I did this a few months ago. Let me put my version of the code up on my GitHub (it’ll include the things I mentioned in my response to @jdenommee above), and try that version.

We’ll get your controller working!
