#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
BlynkTimer timer;
char auth[] = “"; //Auth code sent via Email
char ssid[] = "

char pass[] = "

int flag=0;
void notifyOnFire()
{
int isButtonPressed = digitalRead(D1);
if (isButtonPressed==1 && flag==0) {
Serial.println(“Citofono Squilla”);
Blynk.notify(“Alert : Messaggio 1!”);
flag=1;
}
else if (isButtonPressed==0)
{
flag=0;
}
}
void setup()
{
Serial.begin(9600);
Blynk.begin(auth, ssid, pass);
pinMode(D1,INPUT_PULLUP);
