Thank you to Nerd Nite Austin for a fantastic venue, and my thanks to all of you who were there, creating a palpable enthusiasm for Making Stuff! What a hoot. Resources for ya...
The slidedeck: Hello, Arduino
Samples of my Arduino code are on GitHub, because I like to think out loud in code.

That "hang out and code with other people learning to code" study group is Polyglot Programmers of Austin, our next meeting is tomorrow, and you should totally join us.
Lest you need some motivation for making nerd presentations of your own, check this out. Some months back, I presented at a Dorkbot meeting at the ATX Hackerspace. Afterwards, someone approached me with "I don't know if you remember me, but..." And kapow! Timewarp! Here was my friend from nerd camp, whom I hadn't seen in 20 years! Wow! We've had a blast catching each other up. Then, I'm presenting at Nerd Nite tonight, and after that, another friend from nerd camp comes up and says hello.
Dude, I'm telling you. Take your awesome hobbies, go to nerdy things and present your awesomeness, and fantastic nerdy friends whom you miss will discover you and reconnect with your life. What a delightful unexpected benefit.
