SPECIFICATIONS

GY-521 3-AXIS ACCELERATION GYROSCOPE MODULE

Accelerometer ranges: ±2, ±4, ±8, ±16g
Gyroscope ranges: ± 250, 500, 1000, 2000 °/s
Voltage range: 3.3V – 5V (the module include a low drop-out voltage regulator)

This simple module contains everything required to interface to the Arduino and other controllers via I2C (use the Wire Arduino library) and give motion sensing information for 3 axes – X, Y and Z.

PIN DESCRIPTION

GY-521 3-AXIS ACCELERATION GYROSCOPE MODULE

With this module, you can measure:

acceleration (= speed of movements) in three directions x, y, z;
a rotation or an angles (in three directions);
orientation

VCC (The breakout board has a voltage regulator. Therefore, you can connect the board to 3.3V and 5V sources.)
GND
SCL (Serial Clock Line of the I2C protocol.)
SDA (Serial Data Line of the I2C protocol.)
XDA (Auxiliary data => I2C master serial data for connecting the module to external sensors.)
XCL (Auxiliary clock => I2C master serial clock for connecting the module to external sensors.)
AD0 (If this pin is LOW, the I2C address of the board will be 0x68. Otherwise, if the pin is HIGH, the address will be 0x69.)
INT (Interrupt digital output)

CIRCUIT CONNECTION

The accelerometer measures the acceleration along one direction, while the gyroscope measures the angular acceleration on one axis.

Connections:

VCC -> 3.3 V / 5 V (better)
GND -> GND
SCL -> A5
SDA -> A4
XDA -> NC
XCL -> NC
ADO -> NC
INT -> NC

WORKING

Welcome to the Arduino Based Project which includes GY-521 MPU6050. The analogic pins are not set on INPUT because it’s their default setting. The values read by the analogic pins will be sent to the serial port. Now, to view the output open the Serial Monitor, move the sensor and try to see how the values change. Accelerometers can be used for fun projects, for example to realize a game controller and many more applications.
