The Complete Beginners Guide to the Arduino is, aside from being well worth the price, an excellent learning resource. I highly recommend it, check the website out here:

Arduino Starter Kit Manual

There’s a very interesting paper here about some further ideas in “the internet of things” from the Hammersmith Group. Check it out.

I want to recommend this book as highly as I can: clear, well-illustrated, well-written, informative, intelligent, fun, and full of neat stuff. I actually feel twinges of jealousy reading through it. Platt walks you through Ohms law all the way up to 555 timer chips, sound distortion, and picaxe controllers. It’s awesome. If you’re [...]

Yes, they are all broken because of the addons. No, there’s not really anything I can do about it at this point. The addons changed after I wrote the book and until there’s a second edition, it’s a glaring eyesore and believe something I rue daily. However, there’s plenty that you can do! On XCode [...]

Enjoy

It would look something like Mondo Agency by Cactus

There’s been a small change to the source for the second example of Chapter 13, creating some rotating cubes. The new source is listed below:

The Arduino community continues to wow me! Check out this tutorial for using the VirtualWire libraries to communicate between two Arduino controllers over distance. The author uses it to send messages from an Arduino in his basement to another on the roof of his house. Pretty slick and much more lightweight (though perhaps slightly slower) [...]

These are the slides from a talk I gave last week at Lycoming College in Williamsport PA. Enjoy!

Rossum asks: “Can you make an iPhone out of an AVR? No. Can you get a surprising amount of functionality out of a humble 8 bit processor and a cheap touch LCD? Yes.”
and here’s the result

It’s really awesome work!
