Hi goinheix - Thank you for your nice comments about my posts. As to your question, I only know how to set up the CRGBSet arrays manually. Nice thing about FastLED sketches is that you can experiment with different ideas. Also, I would recommend that you post your question on r/FastLED. Best Regards, Chemdoc77

I have a question: On lines 11-15 you declare some CRGBSet arrays. I need to do the same but they are 100 (it's contiguous groups of 2 LEDs on a 200 LED strip). Should I do this manually or is there a way of making it through a loop?
