Hey I figured this might be a good place to mention this. I've launched a Kickstarter project to fund the creation of a high school level textbook and associated curriculum materials. You can get full details on the kickstarter project page
I've been teaching with Arduino for a few years now and I've been refining my delivery over time. I'm finally at the point where I'm about ready for prime time. If you're interested please consider supporting my project. The other way you can support me is by helping to spread the word.
In addition, I'm always open to suggestions if you have any recommendations for how I could do this better.
