Steps

1. Make sure the components are working properly.
2. Connect the Arduino UNO pin SDA & SCL to accelerometer sensor SDA & SCL pin.
3. Connect the servo motor data pin to the Arduino UNO pin 2.
4. Connect the +5v and ground connections respectively.
5. Check the Arduino program.
6. Check the Circuit Connections.
7. Run the Arduino program.

Arduino Program

#include <Wire.h>
#include <MPU6050.h>
#include <Servo.h>   
Servo sg90;          
int servo_pin = 2;
MPU6050 sensor ;
int16_t ax, ay, az ;
int16_t gx, gy, gz ;

void setup ()
{ 
  sg90.attach ( servo_pin );
  Wire.begin ( );
  Serial.begin  (9600); 
  Serial.println  ( "Initializing the sensor" ); 
  
  sensor.initialize ( ); 
  Serial.println (sensor.testConnection ( ) ? "Successfully Connected" : "Connection failed"); 
  delay (1000); 
  Serial.println ( "Taking Values from the sensor" );
  delay (1000);
}

void loop () 
{ 
  sensor.getMotion6 (&ax, &ay, &az, &gx, &gy, &gz);
  ax = map (ax, -17000, 17000, 0, 180) ;
  Serial.println (ax);
  sg90.write (ax); 
  delay (200);
}

Usage

1. Mobile phones
2. Drone camera stabilization
3. To detect faults in rotator machine
4. To display images in an upright position on screens of digital cameras
