FastLED and LEDStrips.

I want to know if it is possible to loosely simulate the northern-lights with the fastLED library. How can I achieve this:

with the arduino IDE and strip LEDs.


You can do it. They support pallets which would help with the affect, there is a glow example that looks somewhat similar.

The most important aspect of your design will likely be a suitable diffuser to spread the led out. You'll have to experiment ther

Yes you can. Both FastLED and the Adafruit libraries would work. Both come with examples that should give you the skills to achieve exactly what you need to do.

Yes a diffuser will be something you will have to experiment with, even a white piece of tissue paper works well.
