hello

I did an IOT project by Rishabh Jain,

https://circuitdigest.com/microcontroller-projects/iot-based-patient-monitoring-system-using-esp8266-and-arduino

The code i typed was:

#define USE_ARDUINO_INTERRUPTS true    
#define DEBUG true
#define SSID "pulse"     // "SSID-WiFiname"
#define PASS "pulse" // "password"
#define IP "184.106.153.149"      // thingspeak.com ip
#include <SoftwareSerial.h>
#include "Timer.h"
#include <PulseSensorPlayground.h>     // Includes the PulseSensorPlayground Library.   
Timer t;
PulseSensorPlayground pulseSensor;
SoftwareSerial esp8266(10,11);

//Variables
const int PulseWire = A0;       // PulseSensor PURPLE WIRE connected to ANALOG PIN 0
const int LED13 = 13;          // The on-board Arduino LED, close to PIN 13.
int Threshold = 550;           //for heart rate sensor
float myTemp;
int myBPM;
String BPM;
String temp;
int error;
int panic;
int raw_myTemp;
float Voltage;
float tempC;

String msg = "GET /update?key=71L9NBETJ4DRCGKS"; 
void setup()
{
 
  Serial.begin(9600); 
  esp8266.begin(115200);
  pulseSensor.analogInput(PulseWire);   
  pulseSensor.blinkOnPulse(LED13);       //auto-magically blink Arduino's LED with heartbeat.
  pulseSensor.setThreshold(Threshold);   

  // Double-check the "pulseSensor" object was created and "began" seeing a signal. 
   if (pulseSensor.begin()) {
    Serial.println("We created a pulseSensor Object !");  //This prints one time at Arduino power-up,  or on Arduino reset.  
  }
  Serial.println("AT");
  esp8266.println("AT");

  delay(3000);

  if(esp8266.find("OK"))
  {
    connectWiFi();
  }
  t.every(10000, getReadings);
   t.every(10000, updateInfo);
}

void loop()
{
  panic_button();
start: //label
    error=0;
   t.update();
    //Resend if transmission is not completed

  Serial.println(cmd.length());
  esp8266.println(cmd.length());

void getReadings(){
  raw_myTemp = analogRead(A1);
  Voltage = (raw_myTemp / 1023.0) * 5000; // 5000 to get millivots.

                                               // "myBPM" hold this BPM value now.

Serial.println(myBPM);                        // Print the value inside of myBPM. 
}

  delay(20);

  else
  {
    Serial.println("AT+CIPCLOSE");
    esp8266.println("AT+CIPCLOSE");
    //Resend...
    error=1;
  }
}
}

I was getting some errors in the comilaton part. But som one in the forum correcte those errors so the compitaion is done successfully however the data is shown on thingspeak.com and neither the emails are being sent. 

below is the otuput on serial monitor
