Hi,

to calculate resistors for RGB leds in series (say 6 No) do I total the ohms for red green and blue as per the values from the LED series/parallel array wizard (that shows the resistor at the anode/cathode side of the led) to get the required resistor value?

Or is the wizard diagram wrong and I should place a resistor before each red green and blue terminal?


Hope you can help!
Thanks
