Interfacing MPU 6050 Sensor with Arduino UNO

Updated: May 19, 2023

Learn how to interface the MPU 6050 - Accelerometer & Gyroscope sensor with the Arduino UNO board.

Hardware Components:

1. Arduino Uno:

#ArduinoUno board is used for interfacing the input-output elements to construct a project. It is an open-source microcontroller board that can be programmed according to user requirements.

What is Arduino?

Arduino Uno

2. MPU6050 sensor:

MPU-6050 is a 6 axis motion tracking device generally used in smartphones and wearable sensors. It has 3-axis MEMS (Micro-Electro-Mechanical Systems) gyroscope and accelerometer.

Code Explanation -

Download the MPU6050_tockn.h and Wire.h libraries and include them in the Arduino IDE.
In void setup(), initialize the MPU6050 sensor pins and the I2C common port. Start the serial monitor output with a 9600 baud rate.
Using the mpu6050.calcGyroOffsets(), calculate the offset of the sensor.
In void loop(), using the mpu6050.update() function convert the raw data collected from the sensor into useful values.
Using the functions like mpu6050.getTemp(), mpu6050.getAccX, mpu6050.getAccAngleX(), etc. print the respective values obtained from the use of those functions.

Working:

The MPU6050 sensor is interfaced with the Arduino. Accelerometric and gyroscopic parameters are printed on the serial monitor output using the necessary functions.
