“heading_pitch_roll” demonstrates the compass accuracy at 90 degree intervals.The scale rotates beneath the compass needle which is fixed. “compass_rose” demonstrates my graphics “compass rose”.Compass heading accuracy is within +/- 2 degrees. The required magnetometer offsets and scale-factors are calculated and presented in a manner suitable for use with cut-&-paste. The results are shown in a rotatable 3D display. The user is asked to rotate the compass in 6 different orientations. “compass_cal” demonstrates my magnetometer calibration software.The estimated cost for this project is $20 USD. Use my “compass_cal” software and save the resultsĪ compass-heading of +/- 2 degrees is possible using my “compass_cal” software. ![]() Tumble the compass once and save the results.Tumble the compass every time at switch-on.A graphics “compass rose” on your PC screenĬalibration is simple. ![]() The following options are available for displaying the compass heading | pitch | roll: This instructable explains how to build, and calibrate, a tilt-stabilized compass using an Arduino UNO R3 and an MPU-9250 accelerometer | gyro | magnetometer.
