WebSep 27, 2024 · 1. The majority of the time adding a resistor to the data line is completely pointless. It only has an effect if the Arduino and the first WS2812B chip are connected over a long cable. By "long" I'm talking meters, not centimeters. The length of the strip of LEDs is irrelevant as each LED generates a fresh signal to send to the next LED. WebMay 6, 2024 · Each LED-resistor pair is connected to a different output pin. With about 2V across the LED and 3V across the resistor you'd have about 14mA (3V/220 Ohms) coming out of each pin and through each LED-resistor pair and that's OK. If this is going to be your hobby I strongly recommend getting a meter. A cheap meter is better than no meter and … WebExample 1: The blue LED has a typical forward voltage drop of 3.2 V, therefore a 5 Ω resistor is required when using a 3.3 V supply voltage. However, if you are using a 5 V supply voltage, then a 90 Ω resistor is needed. As you can see, the resistor value increases as the supply voltage increases. scotch lembur
