NeoPixels strips in parallel?

Post by bobthenob »

Next question: My project has 9 strips of NeoPixel LED strips; each strip is 36 pixels (1.2m) long.

Can all 9 strips be in parallel, i.e., all share the same data pin of an Arduino Mega? They're all to do the same thing & having them share the same pin would save me a good deal of time.

Thanks,

- Bob

It is certainly possible to wire 2 or 3 in parallel. But 9 may be too much of a load on one pin. One thing that would probably work is to use Flora Neopixels as repeaters: http://www.adafruit.com/products/1260
Wire 3 of them to one pin. Then connect 3 of your strips to the output of each.

Ooh using those as repeaters would actually work?

Yes it will! Just remember that each repeater in the chain will shift your pixel addressing up by 1.
