Atmel introduced the new Arduino Zero controller board, which includes new support for Bluetooth, Wi-Fi and sensors, apparently (I do not yet have details). A couple of weeks ago, I showed how to use App Inventor and Bluetooth to communicate with an Arduino board.
Here is a video clip about the new Zero controller board. I think App Inventor will also play an important role in the “Maker” / do-it-yourself community in terms of linking smart phones to external hardware devices, like this controller.
I am back from Maker Faire and will start catching up over the next few days. I was mostly offline while down there.
