Simple bot v0.1

Here are some pictures of my simple bot. It doesn't do anything special, it just goes forward, turns, goes backwards, turns, etc.

It's arduino powered, and uses a SN754410 H-bridge motor driver chip I bought at SparkFun.com.

Now, I need some batteries... :-)

Update (13/5/08)

These photo's got picked up by blog.makezine.com so I'll add the arduino code for those interested.
I'll try to add the scematics once I finished my terms. (20/6) If you want to try this at home, I recommend to take a look at the datasheet, it will help you a lot :-)
