Not sure, but if I read the article that Bruno Terkady, who is a friend of mine, wrote about using the Azure service bus to work with an Arduino devices doing various things.

Now Bruno, who works much harder at things then I do, beat me to the punch.  I had heard that he had written an article on Arduino, and I was getting a move on Embedded Devices but missed his article (sorry Bruno).

If you didn’t find the article in your Bing search (get those rewards!) then use this:

Now I have to get back to not doing much.
