processes complex 6-axisMotionFusion algorithms. So, now you will be able to decipher the meaning of

6DOF- 6 degrees of freedom.

These MotionTracking devices are designed for the low power, low cost, and high-performance

requirements of smartphones, tablets and wearable sensors.

For the details about the connection schematic and hardware setup, kindly refer to my previous blog.

Now, let's come to the processing software, which will facilitate the 3D visualization of this motion sensor.

Software required:

ProcessingIDE

Considering that you already have installed ArduinoIDE involving two separate IDEs might make you feel a bit

confused. Well, there's no need to panic. Follow the steps below and all your doubts will be cleared up!

Processing IDE, you need to download a special library named "Toxi" for processing purpose. Locating a "Toxi"

file can be very hectic on the world wide web. So, I've made it easier for you by uploading it to my github. Click

on this link and download the file named “toxiclibs-complete-0020”. Next, extract the folder . Copy

the "toxiclibs-complete-0020" folder and paste it under the "libraries" folder of Processing.Cant find

"libraries folder"? then, make one! yeah. if you can't find a "libraries" folder, make a folder and name it as

"libraries". Now, paste your "toxiclibs-complete-0020" folder inside it.Having followed these steps

properly, run the Processing IDE. Time to code!In order to visualise the 3D visualization , you need to first

upload the Arduino code for MPU-6050 (Extract the .ino file from MPU6050_DMP6.rar folder). After having done

so, you need to make certain alterations as below.You need to comment this code which says:

#define OUTPUT_READABLE_YAWPITCHROLL by // #define OUTPUT_READABLE_YAWPITCHROLL

code.You'll see that by default, the line defines it for linux/mac users as:

String portName = "/dev/ttyUSB1";

You need to change String portName to the port on which your Arduino is connected. Refer to Figure 3.
