I have some assorted led's, lots of colors.
What value resister do I add in the circuit with 12 VDC?





Use ohms law. Most LEDs are rated around 20 ma. Personally, I like
to limit them to around 5 - 10 ma. Experiment to see what brightnes
level is acceptable to you. I have ones functioning at only about 2 ma.
