Gyroscope-Arduino That Produces Sound

You will learn how to generate music through an accelerometer and an MPU6050 gyroscope in this article (also referred to as a "gyro sensor")

Installing the Arduino Libraries

You'll require the I2C library and MPU6050 sensor library, which you can access through this file folder

Next, open Arduino IDE and click on Sketch- include library-Add.ZIP library. Add I2C library and MPU6050 folder in your Arduino library.

Once you have these files, click on file-examples-MPU6050-MPU6050_raw.

Upload the code found in the MPU6050_raw and it should display on the serial monitor.

If it's showing the output data, then you can assume the sensor has successfully interfaced with the Arduino.

Adding Music Notes on Arduino

Download music notes. Open the song file of your choice. In my project,I used Furelise.

Then you have to combine the code from music notes file and MPU6050_raw.

You can edit the tempo, number of const int melody, number of notes to include in const int melody. You can also edit the if condition to get more variation with every movement.

Copy the code and edit to your preference.
