| - | * The getSongDuration() function is called in the loop() function, but it is currently commented out (//getSongDuration();). Therefore, the song duration and remaining duration will not be displayed on the LCD screen. | + | * At the beginning, I declared two matrixes that contained the songs and the respective artists in order for them to be displayed on the LCD screen. |

| - MP3 Module Integration: The project successfully integrates an MP3 module with an Arduino board using the SoftwareSerial library. The module is controlled using specific commands sent via the software serial communication. | - MP3 Module Integration: The project successfully integrates an MP3 module with an Arduino board using the SoftwareSerial library.

| - Playback Control: The code enables basic playback control functionalities such as play, pause, next track, and previous track. The buttons connected to the Arduino board trigger these playback commands. | - Playback Control: The code enables basic playback control functionalities such as play, pause, next track, and previous track.

| - | - LCD Display: The project utilizes a LiquidCrystal library to interface with an LCD display. The display is initialized and shows fixed text for "Duration:" and "Remaining:". However, the code for updating the duration and remaining duration on the LCD screen is incomplete or commented out. | + | - LCD Display: The project utilizes a LiquidCrystal library to interface with an LCD display.
