Re: WS2812B How do I control my leds? SOLVED!!!

Nevermind I forgot big_smile

It's been a while since I programmed those fastled leds so I forgot very important line fastLED.show() :DDDD

Anyway turns out that to get the right value from sliders( by default they give out -48 to 52) I needed to do some maths

Anyway solved
