How to Use

1. Power the Sensor: Connect the VCC pin to a power supply (3V to 5V) and the GND pin to ground.

2. Connect I2C Lines: Connect the SCL and SDA pins to the corresponding I2C lines of your microcontroller.

3. Optional Connections: Connect the INT pin to a GPIO pin for interrupt functionalities if required.

4. Initialize the Sensor: Use an appropriate library to initialize and configure the sensor. The following example demonstrates how to use the MPU-6050 sensor with an Arduino.

// Example code for Arduino

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

MPU6050 sensor;

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

  sensor.initialize();
  if (!sensor.testConnection()) {
    Serial.println("MPU6050 connection failed!");
    while (1);
  }
}

void loop() {
  // Read accelerometer and gyroscope values
  int16_t ax, ay, az, gx, gy, gz;
  sensor.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);

  // Print accelerometer values
  Serial.print("aX = "); Serial.print(ax);
  Serial.print(" | aY = "); Serial.print(ay);
  Serial.print(" | aZ = "); Serial.println(az);

  // Print gyroscope values
  Serial.print("gX = "); Serial.print(gx);
  Serial.print(" | gY = "); Serial.print(gy);
  Serial.print(" | gZ = "); Serial.println(gz);

  delay(500); // Wait for half a second before taking another reading
}
