I replaced my closet doors and decided to also place some LED strip lighting in the closets. I look all over for a good controller to turn the LED lights on/off as the closet doors open and close. This seemed like a simple request at first but I soon found that I didn't like any of the comercial solutions. They all seemed to have issues. The solution would be to build my own. Let's face it, it's a lot more fun to build it yourself anyhow.
