This MP3 Program was created using C++ in the Arduino desktop code editor. The user can switch through songs by pressing the button. The video illustrates the functionality of the program. The LCD screen displays the name of the song for a few seconds, and then the song begins to play. The LED lights light up to the music. The Piezo buzzer plays the song. The button is pressed to switch songs. When the song ends, the button is pressed and the next song begins.
