Sound based 'Dancing' LEDs

In this project documentation, I will be explaining you about making Sound reactive 'Dancing' LEDs. This project was inspired by the audio visualizer. This is just for fun, but it can also serve as a sound intensity meter. For this project, we will be needing a Big Sound sensor and 18 LEDs.

To know more about how this works and the setup, please watch the YouTube video posted at the bottom of this page.

Hardware components

• Arduino Uno/ Arduino Nano
• Solderless Breadboard
• Big Sound sensor
• LED (x18) - generic
• Male-to-Male Jumper wires (x13)

Setup

Connections

• Big Sound sensor - A0
• (+) of Big Sound sensor - 5V
• (-) of Big Sound sensor - GND (Ground)

LEDs

The cathode of all LEDs were connected to GND (Ground).
