How do neopixels work
WebAug 30, 2013 · Place a 300 to 500 Ohm resistor between the Arduino data output pin and the input to the first NeoPixel. The resistor should be at the end of the wire closest to the NeoPixel (s), not the microcontroller. Some products already incorporate this resistor…if you’re not sure, add one…there’s no harm in doubling up! WebThe WS2812 and WS2812B requires about 5V to work. The WS2812 should operate at anywhere between about 4V to 7V while the WS2812B should operate at anywhere between about 3.3V to 5V. 5V is readily-available on most boards. The 5V header on an Arduino board, for example, is a perfect voltage supply for the LEDs.
