Let's Make Robots!

What's I2C, how does it work and how to expand a PICAXE Project Board with it.

Hi all, I'm quite new about the things discussed in this site, I've completed successfully the first robot guide that is suggested to new users and now I want to make another step building an hexapod.

Since, as I said, I've followed the beginners robot guide, I have a PICAXE Project Board and a PICAXE 28X1 microcontroller. I'm going to order 18 servos and use 3 of them for every leg (you don't say?!) of the hexapod.
