Danke erstmal für die beiden Antworten.
Das Ardunino habe ich direkt an USB angeschlossen und die Stripe versorge ich mit 5V von einem Computernetzteil.
Vom Netzteil zum Strip die +5V und Masse. Und vom Arduino nur die Datenleitung...
kann da eventuell schon der Fehler liegen?
Wenn ich das Netzteil einschalte flashen die LED´s kurz auf.

Hallo,
ich habe ein Arduino Uno + 5M WS2811. Ich habe gestern das Strip mit 5V angeschlossen und die Datenleitung auf
PIN7 gelegt. Alles hat soweit funktiniert. Jedoch bekomme ich es jetzt nicht mehr zum laufen (alles bleibt Dunkel) . Spannung liegt an.
Kann mir jemand ein Tip geben wie ich das am besten herausfinde?[code#include "FastLED.h"

// Use this sketch to determine what the RGB ordering for your chipset should be. Steps for setting up to use:// * Uncomment the line in setup that corresponds to the LED chipset that you are using. (Note that they
// all explicitly specify the RGB order as RGB)
// * Define DATA_PIN to the pin that data is connected to.
// * (Optional) if using software SPI for chipsets that are SPI based, define CLOCK_PIN to the clock pin
// * Compile/upload/run the sketch// You should see six leds on. If the RGB ordering is correct, you should see 1 red led, 2 green
// leds, and 3 blue leds. If you see different colors, the count of each color tells you what the
// position for that color in the rgb orering should be. So, for example, if you see 1 Blue, and 2
// Red, and 3 Green leds then the rgb ordering should be BRG (Blue, Red, Green).// You can then test this ordering by setting the RGB ordering in the addLeds line below to the new ordering
// and it should come out correctly, 1 red, 2 green, and 3 blue.
