==Overview==
Build a music box here! You can play the music files in the TF card, select the song with Joystic rocker and change volume.

==Schematic==
By reading the analog value, you can detect and judgeg the Joystic's movement in the X-Y direction.At the same time, you can choose the control mode according to the stay time.

==Code==
*Setup 1：Connect the CoreUSB module to your computer and then start the 

Arduino IDE.
[[File:CoreUSB_Ble_pc.jpg|600px|center]]
* Setup 2：Select Files>Examples>mCokie>_203_MusicBox_Joystick
[[File: _MusicBox_Joystick _ino.jpg|600px|center]]
* Setup 3：Click upload button to upload program. When "Done Uploading" 

appears, the program should have successfully been uplloaded into the CoreUSB.

==Software Debugging==
*” audio.h” Audio lib file
*Audio module Serial uses D2, D3
<source lang="cpp">
#include <SoftwareSerial.h>

SoftwareSerial mySerial(2, 3); // RX, TX

#define AUDIO_PORT mySerial
</source>
*Detection rocker value
<source lang="cpp">
int uiStep()         //Change songs
{
  if (analogRead(A0) < 100)  //Y-up
  {
    delay(50);       //50 ms delay
    if (analogRead(A0) < 100)      //
      return 1;      //return 1
  }
  if (analogRead(A1) < 100)    //
  {
    delay(50);       //50 ms delay
    if (analogRead(A1) < 100)  //X-Right
      return 2;      //return 2
  }
  if (analogRead(A1) > 900)    //X-Left
  {
    delay(50);       //50 ms delay
    if (analogRead(A1) > 900)  //
      return 3;      //Return to 3
  }
  return 0;
}
</source>

*OLED displays interface and user can change it.
<source lang="cpp">
 //The main interface can be freely changed. 
void draw()
{
  setFont_L;

  u8g.setPrintPos(4, 16);
  u8g.print("Music_sta:");
  u8g.print(music_status ? "play" : "pause");

  u8g.setPrintPos(4, 16 * 2);
  u8g.print("Music_vol:");
  u8g.print(music_vol);
  u8g.print("/30");
  u8g.setPrintPos(4, 16 * 3);
  u8g.print("Music_num:");
  u8g.print(music_num);
  u8g.print("/");
  u8g.print(music_num_MAX);
  u8g.setPrintPos(4, 16 * 4);
  u8g.print("....Microduino....");
  //u8g.print(rtc.formatTime(RTCC_TIME_HMS));
}
</source>

==Hardware Buildup==
*Setup 1：Using the above diagram as reference, connect the sensors into the 

corrensponding ports on the Hub module.
[[File: _MusicBox_Joystick _hub.jpg|600px|center]]
*Setup 2：Insert a micro SD card into the Audio Shield.
[[File: _MusicBox_Joystick _TF.jpg|600px|center]]
*Setup 3：Stack the Audio Shield and Audio modules.Even though your micro SD 

card may be able to store many songs, the program we provide only supports up 

to 9 songs.
[[File: _MusicBox_Joystick _song.jpg|600px|center]]
*Setup4：Connect the speakers into the Amplifier module.
[[file: MusicBox_Joystick _song_speak.JPG|600px|center]]
*Setup5：Stack the Amplifier, Audio, and Audio Shield modules.
[[file: MusicBox_Joystick _3_speak_E.JPG|600px|center]]
*Setup6：Connect the activated Battery module to your Battery Management 

module.
[[File:CoreUSB_Ble_steup2.jpg|600px|center]]
*Setup7：Stack all the modules together in any order you like (Except three 

Audio modules, They must be together). Congratulations, you have finished 

building the circuit!

==Result==
Control music playback, pause and change songs by using Joystick. You can also build a nice look LEGO Shell.
