9-Axis IMU LESSON 21: Visualizing 3D Rotations in Vpython using Quaternions

In this lesson we show how to use quaternions from the BNO055 to create a visualization in Vpython. The visualization is a complete 3D free body rotation of a rigid body. To build this project you will need an Arduino Nano, and an Adafruit BNO055 Inertial Measurement Sensor.

This is the code we developed in the video posted here for your convenience. This code is for demo purposes only and should not be used in real applications. It is for educational purposes only.

This is the code we developed on the python side to do the visualization from the passed quaternions.
