I was glad to find these forums. DC voltage is what I am primarily interested in when it comes to lighting and my focus and area of interest has mostly revolved around leds. I had a long break from microntrollers and associated projects, but back in the late 90's I started somewhat of an xmas lighting war in my street. It was great and really got the neighbours planning what to do the following year to try and outdo each other. With the changes in LED technology my fascination has always been with RGB devices so I'm looking to incorporate some of those ideas into my xmas lighting this year. Looking forward to continue my adventure and being part of the forums. I am very interested in learning more about DMX and how I can incorporate it into my lighting this year.
