Hi,
i got a strange problem (for me).
for a project i have WS2812B leds build in a lamp.
i wrote code using WS2801 leds because the ws2812b haven't arrived yet.
the leds are controlled with an IR-remote and with the WS2801 strip everything works ok.
but when i change the led to WS2812B the remote doesn't work anymore.
the code it self works, but it goes crazy.
when i push button 1 on the remote it gives value 255
when i change the code to the WS2812B leds it gives complete other codes and everytime you push the same button you get an other value.
the code below is for the WS2801
changes made for the ws2812b are:
the // before "define data_pin 6 " are removed
and in void setup
FastLED.addLeds<WS2801, BGR>(leds, NUM_LEDS);
becomes
FastLED.addLeds<WS2812b, DATA_PIN, GRB>(leds, NUM_LEDS);
the code is maybe not the best but i am not a pro 
hope someone can help me with this, or knows hw to fix it.
