Tutorial: How to control a servo motor using the acceleration sensor?

The purpose of this sketch is to use the MPU6050 acceleration sensor to

control the movement of the servo motor. The acceleration sensor measures

its inclination angle and sends it to the Arduino board. The Arduino board

then adjusts the rotation angle of the servo motor to match the inclination

angle of the MPU6050 accelerometer.

Connections from the Arduino to the breadboard:

• Arduino GND pin → Breadboard ground line

• Arduino 5V pin → Breadboard 5V line

Connections from the servo motor:

• Servo GND pin → Breadboard ground line

• Servo VCC pin → Breadboard 5V line

• Servo signal pin → Arduino pin 3

‍Connections from the MPU6050:

‍

• MPU6050 VCC pin (+ pin) → Arduino 5V pin  

• MPU6050 GND pin (- pin) → Arduino GND pin

• MPU6050 SCL pin → Arduino pin A5  

• MPU6050 SDA pin → Arduino pin A4
