In this lesson we show you how to get a clean calibration on your BNO055 9-axis sensor. In the video below we take you through the coded needed to calibrate the sensor, and a simple technique to quickly get the system properly calibrated.
The code developed in this video will be used in future lessons, and is included below:
The code below is for demo purposes only, and should not be used in any real applications. It just demonstrates how to work with this sensor in benchtop presentations.
