I'm running my 8 rgb (ws2811) diodes on Arduino but they seem to be working only on 3.3pin when I tried powering them from 5v it doesn't work.
I use FastLed library eamples.
I use 10uf capacitor between +- pins and arduino I use resistor (1k ohm between the last DIN pin and Arduino pin 22)
I would appreciate any suggestions. Thanks
