CODE

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

char auth[] = “2f8482b704cf41fbadb23d937ce10777”; // the auth code that you got on your gmail
char ssid[] = “Harsh Home”; // username or ssid of your WI-FI
char pass[] = “ngfbasketball”; // password of your Wi-Fi

void setup()
{
// Debug console
Serial.begin(9600);
pinMode(D1,OUTPUT); //extend these to D8 if you are using a 8 pin relay
pinMode(D2,OUTPUT);
pinMode(D3,OUTPUT);
pinMode(D4,OUTPUT);

digitalWrite(D1,HIGH); // Make it low if you want everything to go off
digitalWrite(D2,HIGH); // in case of a power cut
digitalWrite(D3,HIGH);
digitalWrite(D4,HIGH);
Blynk.begin(auth, ssid, pass);
}

void loop()
{
Blynk.run();
}

CIRCUIT DIAGRAM No.1

NOTE :- Use the given circuit diagram if your Node Mcu is able to supply the necessary 5V to the relay Board. This Setup Does not uses Arduino Uno.


CIRCUIT DIAGRAM No.2

NOTE :- If you DONOT plan on  making a case for the circuit. This uses Arduino as Node MCU didn’t supply enough power to trigger relay ON/OFF.



CIRCUIT DIAGRAM No.3

NOTE :- If you plan to make a circuit enclosed in a case like i showed you in the video
