Lily pad mp3 project works only after upload.

Development Boards Arduino

I got this art project where an old phone is made up to ring randomly and if you pick it up it plays a audiofile and another one if you pick it up during not ringing time. That was a little tricky for me cuz i dont had a clue at all befor this project and i was a beginner. Now that it works i got a lot small informations in my head to make some easy projects and i am about it but i cant find the mistake in this one. It does its job only direct after upload and if u turn it off and on again, more than one time, it is just ringing but not playing an audiofile anymore. I got to upload it again to make it working again.

Maybe its an arduino related issue i thought.

#include <SPI.h>            // To talk to the SD card and MP3 chip
#include <SdFat.h>          // SD card file system
#include <SdFatUtil.h>
#include <SFEMP3Shield.h>   // MP3 decoder chip

//name the pins, elapsed time and output. pin1 = A0, pin2 = A4, pin3 = A5, pin4=1, pin5 = 0
const int ringerPin = A0; // TRIG1 is a free pin
const int onhook = A4;     // TRIG4 is not normally used when not FTDI'ing
const int maxCount = 6;  // ring phone this number of times before stopping
int ringCount = 0;        // variable to count number of unanswered rings
unsigned long lastRing;   // time of last ring start
unsigned long randTime;   // a random time btw 1 and 60 mins
unsigned long nextRing; // time the next ring will start 

const uint8_t volume = 0; // MP3 Player volume 0=max, 255=lowest (off)
const uint16_t monoMode = 1;  // Mono setting 0=off, 3=max

// Create library objects:

void setup() {
  pinMode(ringerPin, OUTPUT);     // connect to transistor driver
  pinMode(onhook, INPUT_PULLUP);  //connect to NC switch, SW = open when onhook
  randomSeed(analogRead(0));      // this starts Arduino's random number generator

  //start the shield
  sd.begin(SD_SEL, SPI_HALF_SPEED);
  MP3player.begin();
}
//ring every 1 to 60 minutes if the phone is down (onhook, arduino gnd and digitalpin connected
//and dont ring if the phone is picked up (no onhook)
void loop()
{
  if (digitalRead(onhook) == HIGH) { // phone is hung up, aka onhook
    // kill any tune that is playing
    MP3player.stopTrack();
    // check to see if it's time to ring the phone
    if(millis() > nextRing){ //onhook is probably still LOW here
      // ring the phone a few times
      ringCount++; // used to stop phone from ringing forever unless answered
      for (int x = 0; x < 15; x++) { //ring for 2 secs
        if(digitalRead(onhook) == LOW){ //if hook was taken off while ringing, quit function and start loop() over with else branch
          goto pickoffstate;
        }
        digitalWrite(ringerPin, HIGH); // turn the solenoid on (HIGH is the voltage level)
        delay(50); // wait for 50 msec
        digitalWrite(ringerPin, LOW); // turn the solenoid off by making the voltage LOW
        delay(80); // wait for 80 msec
      }
      nextRing = millis() + 2500; // phone will ring next after 2500 ms, if hook is taken off in the meantime, it will play the track instantly.  
    }
    if(ringCount > maxCount) {
      // reset next time to ring phone if not answered soon enough
      ringCount = 0;
      nextRing = millis() + random(10000, 1800000);//after ringCount surpassed maxCount, phone won´t ring again for 1 to 60 min
    } 
  }
  else // phone has been picked up, aka offhook
  {
      pickoffstate: ;
    if(ringCount <= maxCount && ringCount != 0) {
      delay(2000);
      MP3player.playTrack(2);
      //in future i wona play a randomly choosen track out of 8 files numbered track002,003,004 - track009,
      //i wona make this working after i know whats the issue now, 
      //why it only does its job direct after upload
      //MP3player.playTrack(random(2, 9)); //not testet this code now
      ringCount = 0;
      nextRing = millis() + random(10000, 1800000);
    }
    else{
      delay(1500);
      MP3player.playTrack(1);
    }
  } 
}

It would be nice if somebody could help me to make this project healthy :slight_smile:
