1. Title: Accelerometer - MPU 6050 and the I2C communication protocol

2. Introduction

The purpose of this project was to introduce students to the I2C serial communication protocol by performing different tasks using Arduino IDE and an accelerometer. The tasks included generating figures of accelerations and angles on the x, y and z directions by moving or rotating the sensor. By the end of this project, students gained an ability to use I2C serial communication to transfer data from the MPU6050 accelerometer to the Arduino.

 
3. Materials and Methods

The Arduino code for I2C serial communication and circuit schematic was provided by Dr. Li on his webpage and can be found here.

Project 6 consisted of the following tasks:

1.     Generate figures that show accelerations on the X, Y, and Z axis separately.

2.     Generate figures that show angles on the X, Y, and Z axis separately.

5. Discussion

All tasks were performed and executed successfully. The excel "data streamer" function was used to stream data to excel and then import it to MATLAB. The ability to use PID I2C communication protocol will be very useful for students throughout their engineering careers.
