How to connect an address led strip to arduino?
I want to collect backlight based on powerbank and Arduino. Everywhere they write that it is necessary to choose a resistor, but I do not know how to choose it. Help pick up. This is an address led strip ws2812b. Powerbank at 4400mah 5v-1000mah. 20 LEDs will be
The LED address strip is switched on from a voltage of 5V, and the control output sets the glow and brightness of each individual LED. If you are talking about a resistor that is connected via an information line, then between the tape input and the output of the arduino they put a resistor of 200-500 Ohms.
