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

It depends on the Vmax of each led....
Some led's have a higher/lower Vmax than others, it depends on manufacture/color, or both.... Figure 20ma to be safe, and an average of 3.0v per led... You should be able to figure it from there...

Calculate to get a feel for the correct value, then use a resistance
substitution box...or a pot to come up with a suitable value. ....Dave "Rich" wrote in message ... I have some assorted led's, lots of colors. What value resister do I add in the circuit with 12 VDC? |
