WebMar 22, 2024 · Three lines will run through every pixel on most RGB led strips: one for power (positive), one for ground (negative), and one for the data line. Their color, not voltage, identifies the last two, so you’ll need to know which color corresponds to the voltage before wiring your RGB led strip. 2. Wiring Process for Rgb Led Strip WebApr 20, 2016 · The LED needs about 10 mA to light brightly and at that current will have nearly 2 V across it. That means we need a resistor to drop the other 10 V. From Ohm's Law we can calculate that R = V I = 10 0.01 = 1 k Ω so that's what we've got. We'll put three ammeters into the circuit to monitor current at every junction.
