WebFeb 22, 2024 · Rearranged, Voltage/current = resistance. If you know the Voltage, Vf, of the LED when it is on, and you are driving from an Arduino pin that outputs 5V, then: (5V - Vf)/current = resistor. With 5mA and say a Vf of 2.5V: (5V - 2.5)/.005A = 500 ohm. You can determine Vf of an LED by using a 5V source and a 1K resistor. Webcircuit contains a resistor R, therefore its analysis is a straightforward exercise in the ﬁrst order circuits.
