Sorry I didn't explain myself better.
I meant that you can put the 5ohm resistor with a 3 watt rating in series on your string to see the amount of current you have. all you will have to do is test the voltage across the resistor and then use this formula to find your current.
I = E/R so the voltage drop across the resistor divide by the resistor value.
BeeforChicken is correct you don't need to add any resistors. What was your purpose to adding the resistor in the first place. I asked that in the earlier post? I don't think you answered it or did I miss it?
I used one because I was troubleshooting and also wanted to know how much current was going pass my LEDs. If you're just building and never will tamper with it just hook everything up without the resistor. Everything should work fine.
hope this helps
thanks
Erick
