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;
  • OLED displays interface and user can change it.
 //The main interface can be freely changed.

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

  u8g.setPrintPos(4, 16 * 2);
  u8g.setPrintPos(4, 16 * 3);
  u8g.setPrintPos(4, 16 * 4);

Hardware Buildup

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

corrensponding ports on the Hub module.
