What is MPU-6050?
The MPU-6050 is a popular integrated circuit (IC) or sensor module that combines a 3-axis gyroscope and a 3-axis accelerometer in a single component.
This module is commonly used in various electronic devices, especially in motion-tracking applications and inertial sensing systems.
The MPU-6050 is capable of measuring acceleration along three axes (x, y, and z) and rotational motion or angular velocity around those same axes. It communicates with other devices or microcontrollers through protocols like I2C (Inter-Integrated Circuit) or SPI (Serial Peripheral Interface).

How MPU-6050 Works?
The MPU-6050 is a popular sensor module that combines a gyroscope and an accelerometer.
Here’s how it works:
- Gyroscope:
The gyroscope in the MPU-6050 measures the rate of rotation or angular velocity around three axes (X, Y, Z). It works based on the principle of Coriolis force.
- Accelerometer:
The accelerometer measures acceleration forces acting on the sensor along the same three axes (X, Y, Z). It operates using microscopic structures that get displaced due to the force of acceleration.
Circuit Connection:
- Connect signal pin of Servo motor with pin 9 of Arduino
- Connect VCC pin of Servo motor with +ve terminal of 9V Battery
- Connect –ve terminal of Battery with GND pin of Arduino through –ve terminal of Servo motor
- Connect VCC pin of MPU-6050 module with 5V pin of Arduino
- Connect GND pin of MPU-6050 module with GND pin of Arduino
- Connect SCL pin of MPU-6050 module with A5 pin of Arduino
- Connect SDA pin of MPU-6050 module with A4 pin of Arduino
