Music Player or MP3 Player with Scrolling Display

The Music Player with Scrolling Display project combines an Arduino, a simple keypad, an LCD, and a buzzer to create a unique music-playing experience.

The system reads inputs from the keypad to select and play predefined music tracks, and a scrolling display showcases the current playing track.

Component List:

Name	Quantity	Component
U1	1	Arduino Uno R3
U2	1	LCD 16 x 2
R1	1	220 Ω Resistor
PIEZO1	1	Piezo
S1	1	Slideswitch
R3	1	1 kΩ Resistor

The circuit consists of a keypad (connected to pins 2-9) for track selection, a buzzer (connected to pin 7) for audio output, and an LCD (connected to pins 8-13) for displaying the current track name.

A resistor network may be included for voltage division. The LCD utilizes custom characters to represent a play icon and track details.
