Hi everybody. today I would like to program an arduino uno to control my neo pixel led strip.I would like to integrate it on my car as on the video: Bande LED Strip d'éclairage arrière - YouTube . being beginner I do not know what code to use can you help me I'm French thank you
The [u]Adafruit website[/u] seems to have the most comprehensive documentation/application information/tutorials.
It's in English but your English looks OK to me... Your writing is a little careless... You didn't capitalize your sentences, but I think you can read & write English. 
You can't be careless when writing computer code.
The FastLED library works great with these LEDs.
Start with examples of the library of choice; you can install both the NeoPixel and FastLed libraries. See how they work and what you can do with them.
Next pick one and start playing around with code; when you get stuck, we're here to help.
Thanks for your help. I will try some examples:)
