Hi Ok so i just ordered some leds for my little brothers pine wood durby car! I got them from digikey but im a little confused how i would calculate the resistor values for them. Basically is the forward voltage the same as the supply voltage? Like do i use the forward voltage for calculting the re…

Calculating led resistance?
