Dimensions: 20mm x 15mm.

The module contains an integrated MPU-6050 circuit with accelerometer, gyroscope and temperature sensor. It communicates on the I 2 C interface , requiring only 2 connections. Every device that uses the I2C interface has its own address. The MPU6050 can select one of two available addresses, linking AD0 to GND or VCC. This connection is usually done on the module board. 

It is useful in your projects that need to detect its movement and intensity, such as games, image stabilization, step counter.

To install the libraries required to use the MPU6050 go to: http://cartearduino.ro/v1/link21.1.0

Use with Arduino

Go to the "Arduino" folder and from there download the ZIP folders: I2Cdev and MPU6050. Install Libraries by following the instructions in the "Libraries in Arduino" chapter (Sketch -> Import Library -> Add .ZIP Library ...) and select your files. After installing the libraries, you can find an example of the program among the Arduino demonstration sketches, as illustrated in Figure 1.

The MPU6050 uses the I2C protocol to communicate with the Arduino plate. 

INT pins can send interrupt requests - the MPU6050 will announce special events. Every device that uses the I2C interface has its own address. The MPU6050 can select one of the two available addresses, linking AD0 to GND or VCC. This connection is usually done on the mode pad. The assembly is shown in Figure 2. For more details, see the datasheet.

This program uses complex filtering and data processing algorithms, calculating the angle of inclination of the mode. The data is displayed on the serial terminal. Load the code on the card and open the terminal. Next, select baudrate 115200. The program will send an initialization message (waiting to receive a character from the keyboard) and then display the angles calculated in the order: yaw, pitch, roll.

In the examples provided, you can also find a simpler program (File -> Examples -> MPU6050 -> MPU6050_raw) that displays unmodified accelerometer and gyroscope data. Compare the two programs to observe the difference.
