The article is great, easy to follow and understand even for a moob like me just getting into microcontrollers and all the things you can do with them. some many other articles on the same project leave steps out or simple lack of details or just out dated and and a waist of time. and the links and the how to videos help even more. I have to say thank you very much I appreciate all your hard work on all your projects and how you are willing to share your knowledge with the rest of us and keeping things interesting, educational, and fun.
