Downloaded FastLed library, tested within the examples FastLED-3.0.3 --> RGBCalibrate, and now this flickers plus i see more LEDS doing things. Can anyone help me?

Try https://github.com/FastLED/FastLED/tree/FastLED3.1.

Beyond that, you really haven’t provided much info to go on.

I think there are mistakes in the file, remove these 2 lines:
leds[random8()%NUM_LEDS] = CRGB(0,0,0);
FastLED.showColor(CRGB::Black);

Have you selected the right LED driver chip type?

5

did you connect the ground of the led strip to the ground of the arduino?

Sorry for providing less info. WS2812B, connected everything like this. http://www.tweaking4all.nl/wp-content/uploads/sites/2/2014/01/arduino_no_computer_power.jpg and selected the right LED driver chip type inside the code. When I check out other examples I even get problems. It’s not a thing to have nothing connected to the end of the strip right?

try what i said - remove the 2 lines i stated. the demo code as it stands is writing the colours then for some reason writing random colours on top. The colours in the rest of the strip are something that sometimes happens when you define less leds than the full length, random glitches when you switch the power on make them light up when connected, it’s only if they’re moving when you’ve got it switched on that means there’s another problem.

Really, Try a different example, as some don’t work well with WS2812B’s because of refresh rate issues. Also make sure you’re using FastLED 3.1. You might also want to try a different pin. Pin 12 works like a charm for me. Finally, try powering it via the USB instead of 5V directly on the 5V pin.
