Arduino LED Dimmer

Posted on Feb 4, 2014

First thing`s first, what software to use I went with CadSoft Eagle primarily because there are lots of tutorials out there covering it, and that seemed like a good place to start. Once I understand the process I can worry about what software I use, but for now, there`s a free-to-use version of Eagle, it`ll do. On my Kubuntu box, installing Eagle

was just a case of installing the eagle  package. For the Mac I had to download the installer from CadSoft`s website. I also downloaded and installedthe Sparkfun Eagle Library and the Adafruit Eagle Library. They really helped to simplify things, though I did find that I had to modify one or two of the packages, mainly just prettifying the silkscreen. I just couldn`t help myself! I`m going to skip theintricaciesof using Eagle, these posts are really just a log of what I`ve been up to and my own commentary on the process. There are plenty of tutorials out there on how to use Eagle. A good place to start would be the Sparkfun Beginning Embedded Electronics Tutorials. Eagle`s UI is unlike any I`ve come across. I`m still not quite sure if it`s genius or justreallyold. I suspect it`s the latter and that the paradigm used to interact with a computer has somewhat shifted since it`s day. However, if it ain`t broke, don`t fix it, and if you`re clever enough to be designing electronics, then you`re clever enough to work it! All I will say is that there are times when it seems staggeringlycounter-intuitive, particularlythe library editor. Also, I found the naming conventions used in some of the component libraries to be perverse. Yeah-yeah, I know, don`t blame the libraries, blame the person who doesn`t know what he`s looking at! All I`m saying is, the component descriptions could be a little more descriptive! Once Eagle was...
