Sound Reactive Cube

Introduction

Today we are going to make a sound Reactive wooden cube. Which will be changing color in perfect sync to the surrounding sounds or vibration.

Hardware required

	Arduino Nano	x	1
	Addressable WS2811 IC DC5V	x	as required
	Mic based Sound Sensor Module	x	1
	White Wood Cube	x	as required	Local carpentry

Theory

The sounds will be picked by the mic module and will be amplified and fed to the Arduino analog pin, we will read the analog pin values and using the fastLED library we will change the colors of the LEDs randomly according to the received values from the mic.
