Im fairly new here, but I got an Arduino about a week ago, and I just love it. So much so, that I thought Id interface it via my favorite language and set of libraries.
Heres a little demo of it running in a quick and ugly theme. http://edjy.wordpress.com/2009/11/19/ardy-arduino-efl-and-python/
For those unfamiliar with the Enlightenment Foundation Libraries, its a robust set of libraries that can be used for interfaces and more. There are a complete set of python libraries to boot. You will be seeing EFL emerging on a number of new handheld devices, but you can use it now in linux, windows and others.
Watch the video for a quick demo :) Thanks, Toma.
