I found a tutorial on Bluetooth for you here:
http://arduino.cc/playground/Learning/Tutorial01
Interfacing with accelerometer(s) here:
http://arduino.cc/playground/Main/InterfacingWithHardware#motion_accelerometer
Does your grad project place any emphasis on spelling, punctuation or grammar?

No Arduino can control an accelerometer. They do whatever they feel like.
On the other hand, any of them can read the data from an accelerometer which is doing its own thing.
