ah one dump question… whats the output voltage of the arduino pin? the data signal should be 5v so far i remember for the specs… my teensy would provide 3.3 without the octows2811 shield…

@Severin_N It is a PC :smiley: - I can not draw :smiley:
yes I have tried more like 3 pins)

OK, give me few minits and i will check a voltage and signal :slight_smile:

but tomorrow, local time is 23:35. I have to go sleep.

The Arduino Pro mini comes in 5v and 3.3v versions.

The LEDs might be SK6812s, try defining them as SK6812 instead.

Good luck

Hi guys :slight_smile:
I solved this issue :slight_smile:
It was arduino problem.
Another arduino (original arduino, not china clone) works well :slight_smile:
Thanks alot for your time
