Abstract

In recent years, the integration of technology into interactive systems has garnered significant attention. Among the many applications, music-reactive LED systems have become popular, offering dynamic visualizations that respond to audio inputs. This paper explores the development and implementation of a music-reactive LED system using Arduino, focusing on real-time audio signal processing and LED control based on the frequency spectrum of the sound. By utilizing Fast Fourier Transform (FFT) algorithms and sound sensors, the system analyzes the audio signal and adjusts the LEDs’ colors and patterns according to the frequency components of the music. The Arduino microcontroller processes the incoming signal, categorizes it into different frequency bands (bass, midrange, and treble), and drives the LED display to create synchronized light effects in real-time. The system was designed to be both cost-effective and easily customizable, making it accessible for DIY enthusiasts and artists. The hardware setup involves RGB LED strips connected to an Arduino board, while the software implementation involves simple coding techniques to integrate the FFT library for audio signal analysis. The proposed design demonstrates the potential of using open-source platforms like Arduino for creating interactive, audio-responsive art installations. This paper concludes by evaluating the performance and flexibility of the system in different use cases, such as home entertainment, concerts, and artistic installations, while also discussing the limitations and future enhancements for further optimization.

Keywords: Arduino, music-reactive LED, real-time audio signal processing, FFT, RGB LED, interactive lighting, sound sensor, audio visualization, microcontroller, LED control system, DIY electronics, interactive art, multimedia installation.
