Hi ! It's not possible per Arduino but you can simply use darker colours for your rpms LEDs, brightness is nothing more than darker colours.

Pure fucking genius.

Never could think about that.

Thanks alot it works.

i'm using 2 different ws2812 led strips. one strip with 16 leds for the rev light, and another strip with 90 leds around my cockpit for different things (like yellow flag, or turn indicators etc.). 

Both are connected to different arduinos.

Now I have a small problem regarding brightness. I would like to keep the rev light around 5-10% brightness (or it will kill my eyes) and the strip around the cockpit at 100%.

But there is only one global slider for brightness which controls all leds.

Is it somehow possible to adjuist the brightness for each strip seperatly?

Thanks!
