MPU-6050 sensor module: A friendly introduction

Inertial Measurement Unit (IMU) (6 deg of freedom)

Arduino IDE

Male/Female Jumper Wires

Arduino Uno Rev3

<p ><span >The InvenSense MPU-6050 is a low-cost, highly accurate inertial measurement unit (IMU) with </span><a href="https://playground.arduino.cc/Main/InterfacingWithHardware/#DOF">six degrees of freedom (DOF).</a><span > IMUs can measure acceleration, inertia and a number of other parameters to allow you to determine their spatial position and velocity. It contains a MEMS 3-axis accelerometer and a MEMS 3-axis gyro in a single chip. It also has an onboard Digital Motion Processor (DMP) which processes complex 6-axis MotionFusion algorithms. This sensor module is also capable of accessing external magnetometers or other sensors through an auxiliary master IIC bus to provide complete 9-axis MotionFusion output. The MPU-6050 sensor module also consists of a temperature sensor but it's less accurate.</span></p><figure><img src=https://projects.arduinocontent.cc/05bd5b55-e94c-4900-a823-64a6de9643af.jpg /><figcaption> </figcaption></figure><h3 ><span >Examples where MPU-6050 may be used</span></h3><ul ><li >Automotive industry - To deploy airbags, Vehicle roll handling</li><li >Game controllers - Wii remote/ Wiimote</li><li >Gimbal/ Camera stabilisation system</li><li >Hard drives</li><li >Personal Digital Assistants - Smartphones, tablets</li><li >Robotics</li><li >Unmanned Aerial Vehicles (UAV) - Drone, helicopters</li><li >Vehicle Navigation</li></ul><h3 ><span >Accelerometer</span></h3><p >This device is used to measure acceleration, the rate of change of velocity of a particular object.

This voltage is internally sampled using a 16-bit analog to digital converter.</p><h3 ><span >Pinout</span></h3><figure><img src=https://projects.arduinocontent.cc/b331d654-287c-4a9c-b3ba-bba4455ec6a9.jpg /><figcaption> </figcaption></figure><ul ><li >VCC - 3.3V DC power supply</li><li >GND - Ground</li><li >SCL - Serial Clock</li><li >SDA - Serial Data</li><li >XDA - Auxiliary Serial  Data (Used when another sensor is connected to this module)</li><li >XCL - Auxiliary Serial Clock (Used when another sensor is connected to this module)</li><li >AD0 - I2C Address bit.
