How to Make Music Reactive LED Lights

Introduction

Music and lights have always been a good combination, and having music reactive LED lights can take your party game to the next level. With the help of Arduino Nano, you can easily make this project yourself. The Arduino Nano is a microcontroller board which is smaller in size and less expensive than the original Arduino board. In this article, we will learn how to make music reactive LED lights using Arduino Nano.

Arduino Nano

Arduino Nano is a small, compact and cost-effective microcontroller board that is based on the ATmega328P microcontroller. It is a miniaturized version of the popular Arduino Uno board and is designed to be used in small electronic projects. The board comes with a USB interface for programming and communication and is compatible with a wide range of sensors, actuators, and other electronic components. It has 14 digital inputs/outputs and 8 analog inputs and is suitable for a variety of projects such as robotics, home automation, and wearable devices. With its small size and low power consumption, Arduino Nano is an ideal choice for prototyping, testing and implementing a wide range of electronics projects.
