Hardware

Built with simple, ready to order parts from common suppliers. Purchase 1 each of the following:

One of the following, needed to program the arduino. (One use only! Borrow from a friend?)

You can also choose to leave the LiPo charger out of the enclosure for small space savings.

Software

This project uses the FreeIMU library to read the motion sensors and calculate sensor-fused orientation.

Arduino

We are using the straight FreeIMU_quaternion example from FreeIMU v0.4. This reads the attached sensors, calculates the AHRS quaternion, and transmits via serial print. I've attached a copy of the FreeIMU_quaternion code here with the baud rate set to 38400, the max rate for the Arduino Pro Mini.

You should only need to upload this to your arduino once.
