Arduvision (I): embedded computer vision with arduino

Ok, its time to share stuff again.
I've spent most of this year's (2014) summer learning how to use a CMOS sensor together with an arduino (ATmega328p) microcontroller, in the process of developing some personal projects.
This is the first of a series of articles to publish my experiencies, and hopefully save someone's time.

In this first post, I'll just release the minimal info that may let you start right away experimenting without reading about how things work. In further articles I'll make detailed explanations of the hardware and software, and the decisions and reasons that led me to my current setup. However, at the end of this post, you may find links to useful documentation.

The items were printed in PLA and cast in brass, and the results are excellent.
