Getting Started with the MPU6050: Gyroscope + Accelerometer Module

If you're building anything that moves, you'll eventually need to measure that movement—and the MPU6050 is one of the best entry-level IMUs (Inertial Measurement Units) to help you do just that.

This tiny 6-axis sensor gives you access to real-time acceleration and rotation data, making it perfect for drones, balancing robots, motion controllers, and wearable tech.

What Is the MPU6050?

The MPU6050 is a popular sensor module that combines:

• A 3-axis accelerometer

• A 3-axis gyroscope

• An I2C interface for easy communication

It’s compact, cheap, and widely supported—ideal for Arduino, ESP32, and Raspberry Pi projects.

Key Features

• Operating voltage: 3.3V–5V

• Communication: I2C

• 3-axis accelerometer range: ±2g, ±4g, ±8g, ±16g

• 3-axis gyroscope range: ±250, ±500, ±1000, ±2000 °/s

• Built-in Digital Motion Processor (DMP)

Sample Arduino Sketch

Install the library first:

Arduino IDE → Tools → Manage Libraries → Search "MPU6050" → Install "MPU6050 by Electronic Cats" or "MPU6050_light"

Basic Code Example:

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

MPU6050 mpu;

void setup() {
  Serial.begin(9600);
  Wire.begin();
  mpu.begin();
  mpu.calcGyroOffsets(true); // calibrate gyro
}

void loop() {
  mpu.update();

  Serial.print("Accel X: "); Serial.print(mpu.getAccX());
  Serial.print(" | Y: "); Serial.print(mpu.getAccY());
  Serial.print(" | Z: "); Serial.println(mpu.getAccZ());

  delay(500);
}

This simple sketch reads accelerometer data and prints it to the Serial Monitor every 500ms.

Project Ideas

• DIY motion game controller

• Self-balancing robot

• Orientation tracking for small satellites

• Posture monitoring system

Pro Tip

For smoother data, consider filtering (e.g., Kalman filter or complementary filter), especially if you're using it for angle calculation or stabilization.

Wrap-Up

The MPU6050 is a tiny powerhouse for motion tracking and feedback. Whether you're prototyping a robot or exploring physics, it’s a must-have in any maker's toolbox.
