which arduino board?

Hi guys

Im a graphic designer student. I have a graduation project to submit which is about programming wireless or Bluetooth accelerometers.(as I don’t have much knowledge about it) But I have no idea about what ardunio board should I get and which accelerometer would you recommend me to buy wireless accelerometer or Bluetooth accelerometer? Also is there any chance to find “ready” written codes for those? (p.s . the program that im using for coding is processing). :-/
