I ran into a similar problem and used another accelerometer as well… The cost was only about 10 US Dollars and seems to work just fine. You can find my post with some guidance from Hanno under this same forum topic under the post titled "Accelerometer Drop- In Replacement". I had fun building my bot and it’s a great learning experience. I’d be happy to share some of the problems I ran into and how I got mine working. I’m almost done, Hanno has posted some suggestions to get mine fine tuned, hope your project is going well.
