Accelerometer project preliminary questions

Thanks very much!

I don't have any experience with I2C/SPI, so that should be fun. I like your suggestion, however, the accelerometers I'm looking at appear to be SMD,which is why I favored the breakout board. Also, the shield you linked claims not to be compatible with MEGA, which I believe would preclude the Uno I already own?

I don't mean to sound ungrateful, just trying to be careful here. Should I look for a dedicated datalogger, or just wire up an SD card as you've said?

Thanks!
