Problems merging 2 codes (blinking light and dfplayer)

Projects General Guidance

This is my wild guess for the code, it can verify/upload but nothing happends:

const byte led = 2;                 // LED pin
const byte sensor = 9;              // PIR sensor pin
bool isActivated = false;

#include "SoftwareSerial.h"
#include "DFRobotDFPlayerMini.h"

SoftwareSerial mySoftwareSerial(10, 11); // RX, TX
DFRobotDFPlayerMini myDFPlayer;

const unsigned long pauseTime = 6000;   // how long between PIR detections
const unsigned long blinkTime = 100;    // how fast to blink led

unsigned long startTime; // time PIR triggered
unsigned long lastTime; // last time we toggled led

void setup() {
  delay (5000);
  pinMode(led, OUTPUT);      // set led pin as output
  pinMode(sensor, INPUT);    // set sensor pin as input

  mySoftwareSerial.begin(9600);
  Serial.begin(115200);

  Serial.println(F("\nInitializing DFPlayer..."));

  //Use softwareSerial to communicate with MP3
  if (!myDFPlayer.begin(mySoftwareSerial)) {
    Serial.println(F("Unable to begin:"));
    Serial.println(F("1.Please recheck the connection!"));
    Serial.println(F("2.Please insert the SD card!"));
    while (true);
  }
  Serial.println(F("DFPlayer Mini online."));

  //Set volume value (From 0 to 30)
  myDFPlayer.volume(30);
}

void loop() {
  if ( isActivated ) {
    // blink led
    if ( millis() - lastTime >= blinkTime ) {
      lastTime = millis();
      digitalWrite(led, !digitalRead(led));
    }

    // check if we have been active long enough
    if ( millis() - startTime >= pauseTime ) {
      isActivated = false; // force PIR to trigger again or not
    }
  }

  if ( isActivated == false ) {
    // check PIR
    int pirSensor = digitalRead(sensor);
    if (pirSensor == HIGH) {
      isActivated = true;
      startTime = millis();
      Serial.println("Sensor Activated");
      Serial.println("DFPlayer Working...");
      myDFPlayer.play(1);
    }
  }
}

Its copied from this working code where an led lights up when distance is <30cm

#include <PCM.h>

#define MIN_DISTANCE 30

int echo = 5; // Pin to echo                          
int trigger = 6; // Pin for trigger
int led1 = 13; // led onboard for test
unsigned long responsetime;
unsigned long distance;



void setup ()
{
  pinMode (trigger, OUTPUT);                     
  pinMode (echo, INPUT); 
  pinMode (led1, OUTPUT);

}

void loop ()
{
  digitalWrite (trigger, HIGH); // We send a 10 microsecond pulse
  delayMicroseconds (10);                        
  digitalWrite (trigger, LOW);                   
  responsetime = pulseIn (echo, HIGH); // And we wait for a pulse back
  distance = responsetime / 58; // Distance calculation in cm

  if (distance <MIN_DISTANCE) {
    digitalWrite (led1, HIGH);        
    delay (35);
    digitalWrite (led1, LOW);

  } 
}

I appreciate your time - im still trying to learn the different styles of coding, but im really lost when its not working :slight_smile:
