// Example sketch for the MPU-6050.
//
// Version 1, 9 August 2021, by Koepel with help from Wokwi community.
//
// Start the simulation and click on the MPU-6050 module to change the values.
//
// Note:
// This example does not use a library with quaternations for the 3D orientation.
// The values are directly read from the MPU-6050 and are used to rotate a cube.
// It is just a fun example. The rotation of the cube is not according to the
// physical values of the accelerometer and the gyro.
