Розробка та реалізація автономного mp3-плеєра на базі мікроконтролера ARDUINO

Abstract

This paper presents the development of a portable autonomous MP3 player based on the Arduino Nano microcontroller. The system features a DFPlayer Mini module for hardware audio decoding and an OLED SSD1306 display for user interface. A specialized power management system using the TP4056 charging controller and TPS63070 buck-boost converter ensures stable operation from a Li-Ion battery. The software, developed in C++, implements an efficient event-driven architecture for track navigation and volume control. Experimental results confirmed high sound quality and reliable performance under varying battery levels.
