I believe this would do it:
R= (Vs - Vled)/I led
Vs: supply voltage
Vled: led voltage
I led: led current
R= (Vs - Vled)/I led
Vs: supply voltage
Vled: led voltage
I led: led current

I'm just above faking it. Barely.
This is the way!

Ohm's law doesn't work with LEDs

Becasue they are diodes, not resistors...

I believe finding the resistance of an LED falls under ohms law. You still use the same formula to calculate it. With an LED, you will just need to do the extra calculation to find the voltage.

Could probably calculate that way as well. I just know that the resistance isn't constant on LEDs as it's dependent on the voltage. Just an extra step...
