MPU6050 Six-Axis Sensor

  The MPU6050 is a 6-axis motion processing component launched by InvenSense. It integrates a 3-axis gyroscope and a 3-axis accelerometer, and includes an I2C interface for connecting to external magnetometers. Using its built-in Digital Motion Processor (DMP) hardware acceleration engine, it outputs complete 9-axis fusion data to the application end via the main I2C interface.
  InvenSense provides a motion processing driver library based on the DMP, which greatly reduces the burden on the microcontroller for motion processing calculations and simplifies programming. This module is widely used in electronic products such as flight controllers and pedometers.

Usage Method

Install Library

To read data from the MPU6050, we can use the MPU6050 library. You can install it through the Arduino IDE's library manager: open the Arduino IDE, go to Tools > Manage Libraries, then search for MPU6050 and install the Adafruit MPU6050 library.
