MPU6050 Module

Course Introduction

In this lesson, we will learn how to use the MPU6050 Module with Arduino.

Note

If this is your first time working with an Arduino project, we recommend downloading and reviewing the basic materials first.

Common Connections:

MPU6050
SDA: Connect to A4 on the Arduino.
SCL: Connect to A5 on the Arduino.
GND: Connect to breadboard’s negative power bus.
VCC: Connect to breadboard’s red power bus.

Writing the Code

Note
You can copy this code into Arduino IDE.
To install the library, use the Arduino Library Manager and search for Adafruit_MPU6050 , Adafruit_Sensor and install it.
Don’t forget to select the board(Arduino UNO R4 WIFI) and the correct port before clicking the Upload button.


/*
  Uses the Adafruit_MPU6050 library to retrieve data from the MPU6050 sensor.
  The process involves initializing serial communication,
  verifying if the sensor is detected, configuring accelerometer and gyro ranges,
  reading sensor data, and displaying acceleration, rotation, and temperature values
  on the serial monitor.

  Board: Arduino Uno R3 (or R4)
  Component: Accelerometer & Gyroscope Sensor(MPU6050)
  Library: https://github.com/adafruit/Adafruit_MPU6050  (Adafruit MPU6050 by Adafruit)
