please i need you guys to help me to add buzzer on coding. i was use nodemcu esp8266 as my microcontroller and flame sensor as my input and the buzzer as a output. went the flame get 1 or high and the buzzer also high, responding to the flame sensor

this is coding. can some of u guys can help me to a add the buzzer

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
BlynkTimer timer;
char auth = “”; //Auth code sent via Email
char ssid = “”; //Wifi name
char pass = “”; //Wifi Password
int flag=0;
void notifyOnFire()
{
int isButtonPressed = digitalRead(D1);
if (isButtonPressed==1 && flag==0) {
Serial.println(“Fire in the House”);
Blynk.notify(“Alert : Fire in the House”);
flag=1;

}
else if (isButtonPressed==0)
{
flag=0;
}
}
void setup()
{
Serial.begin(9600);
Blynk.begin(auth, ssid, pass);
pinMode(D1,INPUT_PULLUP);
timer.setInterval(1000L,notifyOnFire);
}
void loop()
{
Blynk.run();
timer.run();
}

We tend to frown on writing code for people here. However, we are more than happy to help you see your goal.

I will make an assumption that you are using a Piezo buzzer. If so, this link will help you.

Are you using the Arduino ID to program the device? If so, my link above gives clear understanding on how to do this. Even if not using the Arduino IDE, you should be able to port this code.
