Note: The MPU-6050 operates on I2C communication protocol, so you’ll typically connect the SDA and SCL pins to the corresponding lines on your microcontroller or other devices.

mPU-6050 Arduino Code

To use the MPU-6050 with Arduino, you need to connect the sensor to the Arduino board and write a program to read data from the gyroscope and accelerometer. Below are the steps for connecting and programming the MPU-6050 with Arduino:

1. Hardware Connections:

• Connect the 6050 to the Arduino using the I2C interface. Here’s a basic connection guide:
• Connect the VCC pin of the 6050 to the 5V output on the Arduino.
• Connect the GND pin of the 6050 to the ground (GND) on the Arduino.
• Connect the SDA pin of the 6050 to the A4 pin on the Arduino.
• Connect the SCL pin of the 6050 to the A5 pin on the Arduino.
• Make sure you have proper pull-up resistors (usually around 4.7kΩ) for the SDA and SCL lines.

2. Install Required Libraries:

Before writing your Arduino code, you need to install the necessary libraries. The most common library for the 6050 is the “Wire” library, which is usually included with the Arduino IDE.

If you don’t have the library installed, you can do so by going to the Arduino IDE menu: Sketch -> Include Library -> Wire.

3. Arduino Code:

Here’s a simple example Arduino sketch to read data from the MPU-6050 and print it to the Serial Monitor:

#include <Wire.h>

#include <MPU6050.h>

MPU6050 mpu;

void setup() {

  Serial.begin(9600);

  // Initialize the MPU-6050

  while (!mpu.begin(MPU6050_SCALE_2000DPS, MPU6050_RANGE_2G)) {

    Serial.println("Could not find a valid MPU6050 sensor, check wiring!");

    delay(500);

  }

}

void loop() {

  // Read accelerometer and gyroscope data

  Vector rawAccel = mpu.readRawAccel();

  Vector rawGyro = mpu.readRawGyro();

  // Print the data to the Serial Monitor

  Serial.print("Accel: ");

  Serial.print(rawAccel.XAxis);

  Serial.print(", ");

  Serial.print(rawAccel.YAxis);

  Serial.print(", ");

  Serial.print(rawAccel.ZAxis);

  Serial.print(" | Gyro: ");

  Serial.print(rawGyro.XAxis);

  Serial.print(", ");

  Serial.print(rawGyro.YAxis);

  Serial.print(", ");

  Serial.println(rawGyro.ZAxis);

  delay(500); // Adjust the delay as needed

}

This code uses the “MPU6050” library, which simplifies communication with the sensor. You may need to install this library through the Arduino Library Manager (Sketch -> Include Library -> Manage Libraries -> Search for MPU6050).

4. Upload and Monitor:

Upload the code to your Arduino board and open the Serial Monitor (Tools -> Serial Monitor). You should see the accelerometer and gyroscope data being printed to the Serial Monitor.

Feel free to modify the code to suit your specific project requirements.
