Welcome to my third Instructable.

People love listening to music. It is as they say, music reflects our mood. And it is a spectacle to see music become ‘alive’ right before our eyes. Well, that’s what music visualization does.

According to Wikipedia, music visualization “generates animated imagery based on a piece of music. The imagery is generated and rendered in real time and is synchronized with the music we play.”
Music visualization is greatly seen on EDM concerts, where artists team up with VJs (or video jockeys) to create visual spectacles, that can attract and mesmerize the audience. This can be done with video editing and effects software such as Davinci Resolve Fusion and Adobe After Effects. However, this can also be achieved using hardware.

In this Instructable we’re gonna create a simple and easy-to-make audio visualizer using an Arduino UNO, a sound sensor or a microphone, and a 16x2 LCD display. So without further ado, let’s get started

Here are the list of components required for creating this project

- 16x2 LCD display
- Arduino UNO (or Nano)
- Two 1kΩ resistors
- LM393 Sound Sensor Module
- Jumper Cables and Breadboard
- A computer for uploading the code
That’s it. No other components are required.

All the items are easily available on Amazon or any other shopping app. Or you can just go to your nearest electronics dealer to get your components.”
