Hi All, I’m a total newbie electronics guy. Please excuse this silly and hopefully simple question.
I have an Arduino Uno, 5v power supply, and a strip of WS2812B individually addressable LEDS. It says in the tutorial (https://howtomechatronics.com/tutorials/arduino/how-to-control-ws2812b-individually-addressable-leds-using-arduino/) : “…it is recommended to use a resistor of around 330 Ohms between the Arduino and the LED strip data pin in order to reduce the noise on that line, as well as a capacitor of around 100uF across the 5V and Ground to smooth out the power supply.”
Resistors come in Ohms and Watts. So I need a 330 ohm resistor, but which Wattage?
Capacitors come in uF and Voltage. So I need >100uF, but which Voltage?
