Ok, makes sence. Thank u for your help.

And my next question is about your shield option....how do I set the voltage, with another driver? Since the arduino is only low voltage and the rgbs need a higher voltage.

What about something like this

Also have  already purchased a boost driver....http://pages.ebay.com/link/?nav=item.view&id=121106924352&alt=web

Actual input voltage variable between 10 and 14v, sorry depending on running or not (battery storage and alternator)

I have an input voltage between 12 and 14 volts (on a boat).  I am going to use the pwm to change the color of multiple 50w rgb leds.  The vf of the red is 16 - 18v and the green/blue is 24-28v.  The if is 1500ma.

I have a question concerning the drivers in this post.....if the wattage is 16w, how do these work?  Personally I need 500ma, 12v input, 28v out for my leds.  Any help is appreciated.

I have written a gui in c# and am using color picker to populate a button background for a chosen color to send to a jeelabs jeenode with dimmerplug (an i2c device).  I would like to read the current rgb color when the gui is opened and make the button background that color. Then when i choose the new color, send it to the jeenode and update the led color to the button background again. I have gotten this far without requesting help but am now stuck. Like i said, the gui is written, just not the button handlers for this part of the gui. I have a jeelink, jeenode, and dimmerplug, as well as the driver and rgb led all done. I am currently having issues even getting the.  rf12demo to even compile in arduino ide.
