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;
}
