Which Arduino Microprocessor is Right For Me?

I'm doing a science fair project right now, and need a microprocessor which I can receive live data from an accelerometer, send it to another microprocessor, which then uses the data as parameters for controlling an external device. tanks :D

Virtually any Arduino is going to be able to do that. UNOs are readily available.

If you are new to this it would be much simpler if you just use one Arduino to do everything - and an Uno should be perfectly suitable.

Th Uno is the best beginner's Arduino because almost everything (hardware and software) works with an Uno.

...R

Thanks a bunch, and I am pretty new to Arduino, since I'm still in the 10th grade, but fortunately I have not had any problems yet, as I get good help from friends and the internet.
