Hey all, i have drawn what i think is the correct way to hook up my RGB LED in series.
**broken link removed**
The way i see it is that:
- The relay will be turned on by the digital pin on the ardunio using 5v.
- Then the relay will connect and produce the 0v (gnd) to the RED LED pin on the RGB led.
- The Anode will be powered by 12v that will be in series of 19 LED's per 12v
Here is the datasheet:

The black dots are the relay pins. 3 on one side and 2 on the other. From the picture below it seems as though i did hook it up correctly? With the coil being on the side of the 3 dots...

I used 3.3v as the forward voltage since that's the highest it will need to go (blue). So i figured the RED and Green would work just fine with that?
As for the ASCII drawings i changed the specs listed to:
However, i have been told that i would not be able to connect this via series. How can i connect this using parallel?

Code:
12v Source voltage
3.3 diode forward voltage
20 diode forward current (mA)
18 number of LEDs in your array
Solution 0: 3 x 6 array uses 18 LEDs exactly
