  • LED smarter, not harder with this guide in the Adafruit Learn system! I’m often asked for help on a portable or wearable project, the designer insisting “it has to be completely covered in NeoPixels, and able to have them all on white at 100% brightness. But when I do the math it comes out to 1.21 gigawatts. Help!” “The math” in this case is a rule-of-thumb - perpetrated in the NeoPixel Überguide and elsewhere - that each NeoPixel in a circuit may draw up to 60 milliamps of current. It’s a maximum worst case scenario, used in planning wire gauges and battery current and capacity. 100 NeoPixels
