Thank you, it works so well indeed. Can I be so brazen to ask a question?
I have a print with 6 x ws2812 digital LEDs, but I do not have 1 print but 20 prints in total, so 120 x ws2812 leds. all prints are connected with one controller / arduino but I want all prints to do the same. so led1 and led7 led13 led19 do the same as led2, led8, led14 ect. I will add a picture, this is the photo of 1 print with 6 ws2812 LEDs so there are 20 prints of how to make the schedule so that they all do the same.
Thanks
