How to determine what resistor value to use for LED strip I'm trying to use an ESP8266 powered by my computer through USB cable to control a WS2812B LED strip. I've read online that you're supposed to put a resistor before the data channel to help prevent noise but I'm struggling to figure out what the resistor value should be.
I've figured out so far that the LED strip will use a MAXIMUM of 25.8W and that the Vin pin that is powering the LED strip is outputting 5V. I also plan on putting a 470uF capacitor across power and ground.
It seems like people generally just use a resistor around 300 - 500 ohms so I'll just use a 500 ohm resistor. Answer found on another thread. And here as well.
