Software
This project uses the FreeIMU library to read the motion sensors and calculate sensor-fused orientation. I've attached a copy of the FreeIMU_quaternion code here, you only need to upload it once. Be sure to change the baud rate in the program to the max baud for the Arduino Pro Mini, 38400 bps.
