Arduino: How to Use the Gyro-Modul Gy-521 MPU 6050

Hey, what's up!!! For everybody who didn't know that the GY-531 is a small surprise bag, here is a small information box for everyone, who wants to use the gyrosensor GY-521! With this component you can get temperature, the acceleration and the angle.

1. Arduino Mega (U can use every board u want)
2. GY-521
3. Jumper Wires

1. VCC (The breakout board has a voltage regulator. Therefore, you can connect the board to 3.3V or 5V sources.)
2. GND (Ground)
3. SCL (Serial Clock Line of the I2C protocol.)
4. SDA (Serial Data Line of the I2C protocol.)
5. XDA (Auxiliary data => I2C master serial data for connecting the module to external sensors.)
6. XCL (Auxiliary clock => I2C master serial clock for connecting the module to external sensors.)
7. 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.)
8. INT (Interrupt digital output)

To the pin VCC you can connect 5 or 3.3 Volt and to the GND pin the GND on the board

For data connection I'm using the digital pins 20(SDA) and 21(SCL).

The other pins aren't used often, so I skipped them in this tutorial.

I used the libary MPU6050_light to read out the sensor, I only had one problem: The Output through the Serialterminal was the same all the time. To fix this problem i connected to the sda and scl pins on the board.

#include "Wire.h"
#include "MPU6050_light.h"
MPU6050 mpu(Wire);
 
void setup() {
  Serial.begin(9600);
  Wire.begin();
  mpu.begin();
  mpu.calcGyroOffsets();
  Serial.println("Gyro works.");
}
 
void loop() {
  mpu.update();
  float tmp = mpu.getTemp();
  float angle[3] = {mpu.getAngleX(),mpu.getAngleY(),mpu.getAngleZ()};
  float gyro[3] = {mpu.getGyroX(), mpu.getGyroY(), mpu.getGyroZ()};
  float accel[3] = {mpu.getAccX(), mpu.getAccY(), mpu.getAccZ()};
 
  Serial.print("Device Temperature: ");Serial.print(tmp);Serial.println(" Celsius");
  digitalWrite(tmp, "tmp");
  Serial.print("Angles (degrees): x=");Serial.print(angle[0]);
  Serial.print(", y=");Serial.print(angle[1]);
  Serial.print(", z=");Serial.println(angle[2]);
 
  Serial.print("Gyro (degrees/s): x=");Serial.print(gyro[0]);
  Serial.print(", y=");Serial.print(gyro[1]);
  Serial.print(", z=");Serial.println(gyro[2]);
 
  Serial.print("Acceleration (g aka 9.81m/s^2): x=");Serial.print(accel[0]);
  Serial.print(", y=");Serial.print(accel[1]);
  Serial.print(", z=");Serial.println(accel[2]);
  Serial.println("");
   
  delay(1000);
   
}

If by turning the sensor around, the values don't change, please check your pin connections.
