   Sketch → Include Library → Manage Libraries

3. Search for:

   MPU6050

4. Install a compatible library

MPU6050 Arduino Code Example

The following example reads accelerometer and gyroscope values from the MPU6050 sensor.

    #include <Wire.h>
    #include <MPU6050.h>

    MPU6050 mpu;

    void setup() {
      Serial.begin(115200);

      Wire.begin();

      mpu.initialize();

      if (mpu.testConnection()) {
        Serial.println("MPU6050 connected successfully");
      } else {
        Serial.println("MPU6050 connection failed");
      }
    }

    void loop() {

      int16_t ax, ay, az;
      int16_t gx, gy, gz;

      mpu.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);

      Serial.print("Accel X: ");
      Serial.print(ax);

      Serial.print(" | Accel Y: ");
      Serial.print(ay);

      Serial.print(" | Accel Z: ");
      Serial.print(az);

      Serial.print(" | Gyro X: ");
      Serial.print(gx);

      Serial.print(" | Gyro Y: ");
      Serial.print(gy);

      Serial.print(" | Gyro Z: ");
      Serial.println(gz);

      delay(500);
    }

How the Code Works

Wire.begin()

Starts I2C communication between Arduino and MPU6050.

mpu.initialize()

Initializes the sensor.

getMotion6()

Reads:

• Accelerometer X/Y/Z
• Gyroscope X/Y/Z

The values are printed to the Arduino Serial Monitor.

Serial Monitor Output

Example output:

Accel X: -120 | Accel Y: 340 | Accel Z: 16384 | Gyro X: 12 | Gyro Y: -8 | Gyro Z: 3
