Arduino Sample Code

This example reads raw accelerometer and gyroscope data from the MPU-6050 using the I²C interface. Upload the code to your Arduino board and open the Serial Monitor at 9600 baud to view the X, Y and Z-axis readings.

#include <Wire.h>

#define MPU6050_ADDR 0x68

void setup() {
  Serial.begin(9600);
  Wire.begin();

  // Wake up the MPU-6050
  Wire.beginTransmission(MPU6050_ADDR);
  Wire.write(0x6B);
  Wire.write(0);
  Wire.endTransmission(true);

  Serial.println("MPU-6050 Initialized");
}

void loop() {
  int16_t AcX, AcY, AcZ;
  int16_t GyX, GyY, GyZ;

  // Start reading accelerometer and gyroscope data
  Wire.beginTransmission(MPU6050_ADDR);
  Wire.write(0x3B);
  Wire.endTransmission(false);
  Wire.requestFrom(MPU6050_ADDR, 14, true);

  AcX = Wire.read() << 8 | Wire.read();
  AcY = Wire.read() << 8 | Wire.read();
  AcZ = Wire.read() << 8 | Wire.read();

  // Skip temperature data
  Wire.read();
  Wire.read();

  GyX = Wire.read() << 8 | Wire.read();
  GyY = Wire.read() << 8 | Wire.read();
  GyZ = Wire.read() << 8 | Wire.read();

  Serial.print("Accelerometer: ");
  Serial.print("X = ");
  Serial.print(AcX);
  Serial.print(" | Y = ");
  Serial.print(AcY);
  Serial.print(" | Z = ");
  Serial.println(AcZ);

  Serial.print("Gyroscope: ");
  Serial.print("X = ");
  Serial.print(GyX);
  Serial.print(" | Y = ");
  Serial.print(GyY);
  Serial.print(" | Z = ");
  Serial.println(GyZ);

  Serial.println("-------------------------");

  delay(500);

1. What is a MPU-6050 Triple-Axis Accelerometer & Gyroscope Module?

• The MPU6050 is an IMU (Inertial Measurement Unit) device. It's a six-axis motion tracking device that uses data from a three-axis accelerometer and a three-axis gyroscope to calculate movement. The most significant benefit of this board is that it includes a digital motion processor. The importance of the DMP (Digital Motion Processor) is that it handles extremely complex calculations and operations on its own, freeing up the microcontroller's time. It offers motion data such as roll, pitch, yaw, angles, landscape, and portrait sense, among other things.

2. What is the use of MPU6050 sensor?

• MPU6050 is a three-axis accelerometer and three-axis gyroscope Micro Electro-mechanical system (MEMS). It aids in the measurement of velocity, orientation, acceleration, displacement, and other motion-related features.

3. How does the MPU6050 Accelerometer work?

• An accelerometer works on the principle of the piezoelectric effect. Consider a cuboidal box containing a ball. Because of gravity, if we move or tilt the box ball inside the box, it will fall on the box's walls. Similarly, IMUs like the MPU6050 contains MEMS (micro-electromechanical systems) that work in the same way as the cuboidal box with the ball inside.

4. How does the MPU6050  Gyroscope work?

• It works on the principle of Coriolis acceleration. Imagine that there's a fork-like structure that's in an exceedingly constant back-and-forth motion. The crystals experience a force in the direction of inclination whenever you try to tilt this arrangement. The inertia of the moving fork is frequently the cause. As a result, the crystals produce a current in accordance with the piezo effect, which is amplified.
