Example Code for Arduino-MP3 Music Player

Hardware Preparation

• Vortex Robot, SKU:ROB0116
• micro USB cable

Software Preparation

• Arduino IDE, Download link

Other Preparation Work

1. Unscrew the screw and open the USB programming port.
2. Turn on Vortex power switch, and plug in the Micro usb cable, it will install the driver automatically if you have installed Arduino IDE. If not, you can find it in the driver file in Arduino IDE folder-->Drivers folder.
3. There is a switch close to the USB port, make sure the trigger is close to the USB side. This is MP3 switch, we'll teach you how to add new song in the following chapter.
4. Open your Arduino IDE, select "Arduino UNO" and right "COM port" in Arduino IDE, now you can enjoy coding.

 2.This code is tested on vortex V1.0.
 ****************************************************/
#include <SoftwareSerial.h>
#include <VortexMp3.h>
#define MP3_VOLUME 0x10
void init(){
    mp3.Init();
    mp3.setVolume(MP3_VOLUME);
}
void setup() {
  // put your setup code here, to run once:
  init();
}
static int musicState = 1;
void loop(){
  // put your main code here, to run repeatedly:
  mp3.player(musicState);
  musicState++;
  if (musicState>=20){
    musicState = 1;
  }
  delay(1000);
}

Additional Information

1. Turn the switch trigger to the opposite side (away from the USB port).
2. Connect Vortex to your computer via USB port. and it will appear a new flash disk.
3. Rename your voice or your song file, and put them in the disk.

NOTE: The MP3 chip recognizes the file by the modified time, not its name, so you will need to rank the file again! Just cut all file outside, and move them in the disk in order. |
