Interfacing Arduino Uno with MPU6050 Breakout board by Sparkfun


Its time for me to post about my work. So as I mentioned in my abstract, I will be working with low-cost IMUs. Last week, we procured Sparkfun’s MPU6050 IMU. It costs around $40 ( shipping not included). You can view the IMU here.

Hardware Connections: The connections are pretty simple as MPU6050 follows I2C. So I connected VDD and VIO of MPU6050 to 3.3V from the Arduino board. Note that do not connect VIO to 5v of Arduino without using a resistor, else you will fry your MPU6050 board. Next, connect SDA ( Serial Data ) pin from MPU6050 board to Analog pin 4 and the SCL ( Serial Clock ) to Analog pin 5. Lastly connect Ground to your Arduino ground and your hardware connections are good to go!😀

Code: Since I am pretty lazy to write my code, I forked Jeff Rowberg’s awesome library. Yeah it works with an MSP too! You can install the library easily on the Arduino board. If you find some difficulty, you can follow these steps:

  • If you have freshly installed the Arduino IDE, I suggest you save a simple code. It can be any code.
  • Once you have saved, press Ctrl+K in Arduino IDE. It will open up the sketch folder. Usually it’s located in Home directory or Documents.
  • Go to the sketchbook folder -> libraries and copy the I2Cdev and MPU6050 folder from Jeff’s code.
  • Close and restart Arduino IDE. You should be able to see your library in the Examples folder.

I will attach a small screenshot of the sample program – MPU6050 s raw data.

My next step will be to interface more than one MPU to the Arduino board and save their data. Once done with that, I can try to make some sense of the data which I will receive. Till then adios!

    I’ve tried to connect MPU6050 to Arduino but the led still red, can you help me?

    1. Hey!

      Are you using SparkFun’s MPU6050 breakout board?

  5. Hi there would you mind letting me know which webhost you’re working with? I’ve loaded your blog in 3 different web browsers and I must say this blog loads a lot quicker then most. Can you recommend a good hosting provider at a honest price? Kudos, I appreciate it!

    Hi thanks so much for codes but I have some problems.When I run this program,I get
    C:\Users\Serbay\Documents\Energia\libraries\MPU6050\MPU6050.cpp: In member function ‘bool MPU6050::writeMemoryBlock(const uint8_t*, uint16_t, uint8_t, uint8_t, bool, bool)’:

    Do you know anything about this problem ?

  8. HI, add the i2cdevlib.h files in the MPU folder. I had the same issue.

  9. hi!
    I connect my arduino to the mpu 6050 in this way:
    VDD and VIO of MPU6050 to 3.3V from the Arduino board.
    SDA ( Serial Data ) pin from MPU6050 board to Analog pin 4.
    SCL ( Serial Clock ) to Analog pin 5.
    Ground – ground .
    as you write here…
    i try to use this libarary:
    and i get zeros!!!
    what’s wrong!?!?!?
    thank you,

    If some one is interested and wants a simple implementation of MPU6050, they can also have a look at this simple Library,
    It also explains angle calculation combining gyroscope and accelerometer measurements to avoid drift problem.

  11. Hello! Good day, Me and my groupmates are usually making 2 wheel Balancing Robot as our final project and we are using MPU 6050 Breakout board, Sir After Installing library in arduino. How can i connect it to a stepper motor? Is there any code to add in the library? we need your ideas. thanks!

    1. Interfacing stepper motor and using MPU605 are two completely different experiments. MPU6050 enables you to get the gyro and acceleration values from an object.

      If you are wondering how to interface a stepper motor to your project using arduino, I am sure there is a library for the same.
