Nano + ws2812b

I need help... How to connect two ws2812b led stripes (60leds per meter) to arduino nano with adafruit neopixel library without need to connect second stripe to first. I need two independent stripes on others pin's. Any complete code with rainbow cycle? :|

Connect the data from each to a separate I/O pin. Adafruit has codes and guides.

I know but.

Adafruit_NeoPixel strip = Adafruit_NeoPixel(60, 2, NEO_GRB + NEO_KHZ800); Adafruit_NeoPixel strip2 = Adafruit_NeoPixel(60, 3, NEO_GRB + NEO_KHZ800);

But what do I have to add to the loop to handle two strip? ;/

Given the impression that you haven't tried anything and have run out of ideas, maybe you should explain why you believe you need them run as separate strips, because chances are you're wrong. Explain what you are trying to achieve, use your best vocabulary. 'Rainbow' doesn't explain it.
