LED Fixture Revision

Posted on Posted in Electronics

The control system for this project involves a lot of research and programming effort. Development was starting to drag me down since progress was going slowly, so the LED fixture got some attention. I knew it was going to be a rat nest, but I didn’t think it would turn out as bad as it […]
