Quaternion Compass #Arduino

lingib shared this project on Instructables

This instructable explains how to build, and calibrate, a tilt-stabilized compass using an Arduino UNO R3 and an MPU-9250 accelerometer | gyro | magnetometer.

The following options are available for displaying the compass heading | pitch | roll:

  • Serial Monitor
  • LCD display
  • A graphics “compass rose” on your PC screen

Calibration is simple … three methods are provided:

  • Tumble the compass every time at switch-on
  • Tumble the compass once and save the results
  • Use my “compass_cal” software and save the results

A compass-heading of +/- 2 degrees is possible using my “compass_cal” software.

The estimated cost for this project is $20 USD.
