R = V / I can tell me what resistor to use for one LED, but I have different types of LED's each with different resistances. For my example I'll use one purple and one blue. When I put the purple one in the circuit the blue one goes out because there is less resistance through the purple LED I assume.
So i'm wondering how would I set up a circuit to handle different colored LED's, and keep them all bright. I noticed I can add a resistor to the purple one to let the blue one and purple one light, but how do you figure out the proper resistors for each LED?
Thanks!
