Hello guys.

Please help me solve this problem.

I bought this MP3 player in aliexpress:
http://www.aliexpress.com/item/Mini-MP3-Audio-Module-for-Ardunio-with-3W-Amplifier/32322509650.html

I'm refurbishing an old radio an antique car to play MP3.
I like to know if any of you can help me in a sketch to show the music that's playing on 16x2 LCD screen.
I do not really understand programming. Only old cars. :confused:

The address of the datasheet is this:
http://www.trainelectronics.com/Arduino/MP3Sound/TalkingTemperature/FN-M16P%20Embedded%20MP3%20Audio%20Module%20Datasheet.pdf

Please help me.
Thanks.

What code do you have to make it play music?

Hello. Thank you for your response.
To play the music it is possible to do without the Arduino. With external buttons according to the manufacturer's information.
I just read the name of the song being played and display on the LCD.

I don't see that there is a way to ask the device which track it is playing. Nor is there a way to ask it which folder the track is in.

I want to use the Arduino to read via TX RX, the music that is playing.
Because on the device there are query commands.
I believe that with the Arduino I send a command via TX for module, and read the answer via RX and show it on the LCD display.

Yes, if you connect the device to the Arduino correctly.

Which one(s) give the name of the track?

I think it is: 0x4c

I tried to send the value 0x01 (play next) for the Mp3 player for serial, but nothing happened.
How do I send this value?

// Programa : Display LCD 16x2 e modulo I2C
// Autor : Arduino e Cia

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

// Inicializa o display no endereco 0x27
LiquidCrystal_I2C lcd(0x3f,2,1,0,4,5,6,7,3, POSITIVE);

void setup()
{
lcd.begin (16,2);
Serial.begin(9600);
}

void loop()
{
Serial.write(0x01);

delay(5000);

}

Looks to me that you need to send 10 bytes for a command, not just 1.
The command byte is just byte 4 of the 10 bytes needed.
