Is it possible to scale the brightness of a show like the raibow with a slider in the blynk app?
I am a total noob and did try some things(copy paste stuff only) but that did not work. I am using the code from the attached link to control my led strip.
The strip is in my bedroom, but when a show is on it will light up the whole bedroom and it aint fancy anymore.

So anyone any thoughts?

Yes, here’s a Blynk example that has adjustable brightness using a slider.

Also note, fill_rainbow aways uses full brightness (and saturation) so if you want to darken it some (without using the master brightness control) you have to manually fade the brightnes. Example:
