Software Debugging

  • ” audio.h” Audio lib file
  • Audio module Serial uses D2, D3
#include <SoftwareSerial.h>

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

#define AUDIO_PORT mySerial
  • Detection rocker value
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;
}

  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));
}

Hardware Buildup

  • Setup 1:Using the above diagram as reference, connect the sensors into the

corrensponding ports on the Hub module.

  • Setup 2:Insert a micro SD card into the Audio Shield.
MusicBox Joystick TF.jpg
  • 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.

  • Setup6:Connect the activated Battery module to your Battery Management

module.

  • 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!
