Hi everyone,
I’m totaly new on this community, and I need your help ! I’m working on a small project, I have 5 strip ws2812b Leds manage by an arduino Uno. I succeeded to light them using FastLed library.

I have 2 questions :

-How to choose the intensity & the color of one LED ?
I tried with " FastLED.showColor(CHSV(hue++, 255, 255)); " but I don’t really understood how it works.

-I would like to scroll text from the right to the left. Is it possible with this library ? I guess “yes” but how ?

Thanks for your help :slight_smile:

@Kevin_O_Neill HSV stands for hue, saturation and value. Fastled works on a huge range of zero to 255 which maps to 0-360 on your color wheel. The second parameter is the saturation - less means a greyer colour and the last is the intensity or value. Less means blacker / darker.
