What up everybody!

This is just to let you know that I successfully added MQTT support posting data to the cloud! I've updated the Github library which includes a new version of the IoT_Example sketch that allows you to publish GPS, temperature, and supply voltage data to their respective topics via MQTT with username and password authentication. Currently only the connect and publish commands work but I'll be working on getting subscribe and receive functionalities up and running as well as adding support for AWS IoT. So far I have tested with cloud MQTT and it works great! I might also post a little YouTube video on MQTT after I get the new features implemented.

Anyway, lots of stuff going on here and I'm definitely staying busy. Also remember that my Indiegogo campaign is launching in less than 6 days! Please support my tinkering by spreading the word and contributing to my campaign when it launches!
