LED Light via USB?
I've been searching about, and this seems to be quite the vibrant community for DIY gadgets. I'd like to have as final product, a led light connected to a PC via USB - that has a software-controlled dim functionality (ie, 1 is on, 0 is off, values valid 1 < x < 0). I'm a seasoned programmer, but the hardware side of things has always been a mystery.
Where to begin? Is this a complex project?
