Adafruit_NeoPixel strip_a = Adafruit_NeoPixel(16, 5);

Adafruit_NeoPixel strip_b = Adafruit_NeoPixel(16, 6);

The above declares two distinct NeoPixel objects, one each on pins 5 and 6, each containing 16 pixels and using the

implied default type (NEO_KHZ800 + NEO_GRB).

Can I connect multiple NeoPixel strips to the same Arduino pin?

In many cases, yes. All the strips will then show exactly the same thing. This only works up to a point though…four

strips on a single pin is a good and reliable number. If you need more than that, individual NeoPixels can be used as

buffers to “fan out” to more strips: connect one Arduino pin to the inputs of four separate NeoPixels, then connect

each pixels’ output to the inputs of four strips (or fewer, if you don’t need quite that many). If the strips are 10 pixels

long, declare the NeoPixel object as having 11 pixels. The extra “buffer” pixels will be at position #0 — just leave

them turned off — and the strips then run from positions 1 through 10.
