Recursive link in README

[riban-bw]

The README has a link to http://damienclarke.me/code/posts/writing-a-better-noise-reducing-analogread which redirects back to GitHub hence is of little use. Is the text of the referred article available? Maybe it could be added to the GitHub wiki.

Agreed. Regarding reading the article, the internet archive comes to the rescue: https://web.archive.org/web/20170409184051/http://damienclarke.me/code/posts/writing-a-better-noise-reducing-analogread
