Introduction to MPU6050
- MPU6050 is a microelectromechanical system (MEMS), it consists of a three-axis accelerometer and a three-axis gyroscope. It helps us to measure velocity, orientation, acceleration, displacement and other motion-like features.
- MPU6050 consists of Digital Motion Processor (DMP), which has the property to solve complex calculations.
- MPU6050 consists of a 16-bit analog-to-digital converter hardware. Due to this feature, it captures three-dimensional motion at the same time.
- This module has some famous features which are easily accessible, due to its easy availability it can be used with a famous microcontroller like Arduino. Friend if you are looking for a sensor to control the motion of your Drone, self-balancing robot, RC Cars and something like that, then MPU6050 will be a good choice for you.
- This module uses the I2C module for interfacing with Arduino.
- MPU6050 is less expensive, Its main feature is that it can easily combine with an accelerometer and gyro.

I2C Protocol
As we earlier discus that MPU6050 works on I2C protocol, now discuss this protocol.- MPU6050 was first introduced by the Philips semiconductors in 1982. For sending and receiving data between two or more devices we need a path which called BUS. I2C is a bidirectional two-wire bus which use to send data between integrated circuits.
- I2C consist of three data transfer speed which is, standard, fast-mode, and high-speed mode. I2C sports 7 bit and 10-bit address devices.
- I2C is the best choice where simplicity and low manufacturing cost are more important than speed.
- For a better understanding of how I2C protocol works, let's see is a picture.
