Arduino - MPU6050 GY521 - 6 Axis Accelerometer + Gyro (3D Simulation With Processing)

* In this tutorial we will learn how to use MPU6050 6 Axis Accelerometer + Gyro module and GY 521 breakout boards.

* Also we will install the necessary libraries to Arduino IDE.

* And last, we would run the simple simulation with this module using the Processing.

* We can make Quadcopter Drone, RC Plane and Robotic projects using with the MPU6050 module.

Step 2: About MPU6050 Breakout Board GY-521

* The MPU-6050 sensor contains accelerometer and gyro in a single chip.

* The module captures the x, y, and z channel at the same time.

* The sensor uses the I2C-bus to interface with the Arduino.

* GY-521 modules has a voltage regulator.

* Some GY-521 modules have the wrong capacitor (or a bad capacitor) and that results into a high noise level

* In this module I bought, I did not encounter any problems.

* For more information about possible problems, http://forum.arduino.cc/index.php?topic=394691.0

Step 3: Connections

* The MPU6050 communicates with the Arduino through the I2C protocol

* The MPU6050 is connected to the Arduino as shown in the following diagram

* Connect the Arduino digital 2 input to the pin labeled as INT on the MPU6050.

* Then we need to set up the I2C lines. Connect the pin labeled SDA on the MPU6050 to the Arduino analog 4 (SDA) input and the pin labeled as SCL on the MPU6050 to the Arduino analog 5 (SCL) input

Step 4: Install I2Cdev & MPU6050 Libraries

* Jeff Rowberg wrote some Arduino libraries to obtain the accelerometer / gyro data and handle all the calculations

* We need only I2Cdev & MPU6050 Libraries for this tutorial

* https://github.com/jrowberg/i2cdevlib/zipball/mast...

* First unzip the .rar file, find the Arduino folder within it and copy the two folders "I2Cdev" and "MPU6050"

* Paste to your Arduino "libraries" folder in the following directory C:\Users\YourName\Documents\Arduino\libraries

Step 5: Uploading the Code and Testing the MPU6050

* Then open the Arduino IDE and in the examples section, you can find MPU6050_DMP6 within MPU6050

File –> Examples –> MPU6050 –> Examples –> MPU6050_DMP6

* Plug your Arduino Board to your PC

* You should set the baud rate of 115200 for Serial Monitor

* Select the appropriate COM Port and upload the sketch

* Open the Serial Monitor and set the baud rate of 115200

* Now, you’ll see a line saying “Send any character to begin DMP programming and demo.” Just type in any character on the serial monitor and send it

* And you should start seeing the yaw, pitch, and roll values coming in from the MPU 6050

* Also, you will need to wait about 10 secs before you get accurate values from the MPU6050. After which, the values will begin to stabilize.

Step 6: Show the MPU6050 Values As 3D Simulation Using the Processing Software

* To simulation the 3D model in processing, you need to comment the line in the Arduino MPU6050_DMP6 code which says

* #define OUTPUT_READABLE_YAWPITCHROLL by //#define OUTPUT_READABLE_YAWPITCHROLL

* And uncomment the line which says

* //#define OUTPUT_TEAPOT by #define OUTPUT_TEAPOT

* Select "save as" and choose where you want to save the modified code

* Then upload it again to the Arduino

* To show the 3D simulation of the data from the MPU6050, you need to install the Processing software, you can find download link in the video description. https://processing.org/download/?processing

* Processing is similar to Arduino, except for a couple of functions. Processing is mainly used for visualizing data.

* For more about the Processing, you can watch the tutorial below

* After installing the Processing IDE, we will need to download a library called 'ToxicLib'. This library is necessary for our the MPU6050 processing example.

* The latest version of the ToxicLibs library is here: https://bitbucket.org/postspectacular/toxiclibs/d...

* Unzip ToxicLibs and place all the contents to the processing folder (yourProcessingFolder - > modes -> java -> libraries)

* Last of all, open the Processing Software

* Next, you have to open the Processing example for the MPU6050

* Open the folder where you added the MPU6050 library for the Arduino

(MPU6050 -> Examples -> MPU6050_DMP6 -> Processing -> MPUTeapot)

* Click the RUN button and the system should calibrate for about 10 seconds

* Then you can test the yaw / pitch / roll of the MPU6050
