Share a good way to write interface under the bare computer

Is that code usable with an Arduino ? I don't understand your post.
Please tell that you have a shop, and a forum and you test and try things. Please don't link to a zip file with unknow contents.

I suggest you use your blog or create learning pages at the shop website and tell there about your ideas and tests.
If you code is very usefull for a service entry, you might make a youtube movie to explain and show it.
If you have something special, you can tell us about it and link to your own page.

I'm not a moderator, but I think that a commercial link now and then is okay.
