In this tutorial, we are going to make IoT Home Automation System using Blynk NodeMCU ESP8266

Introduction

The term "home automation" refers to a system that automates the control of household equipment. We can now control household appliances from anywhere on the globe using a mobile device, a laptop, or the internet. All of these types of systems are growing more popular since they give versatile functionality which can be readily configured by anybody according to their needs, hence why all IoT systems are getting more popular.

In this electronic project, we are going to make an "IoT Home Automation System" using Blynk App and NodeMCU ESP8266 Microcontroller.

ESP8266 Code

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

char auth[] = "Sz5eLNB-rcd9w43wBRMYkhI28eu4ASEY"; // Enter your Auth Token 
char ssid[] = "Circuits DIY"; // Enter your WIFI name
char pass[] = "03433212601"; // Enter your WIFI password

//Get the button value
BLYNK_WRITE(V0) {
  digitalWrite(D0, param.asInt()); // Relay 1
}
BLYNK_WRITE(V1) {
  digitalWrite(D1, param.asInt()); // Relay 2
}
BLYNK_WRITE(V2) {
  digitalWrite(D2, param.asInt()); // Relay 3
}
BLYNK_WRITE(V3) {
  digitalWrite(D3, param.asInt()); // Relay 4
}

void setup() {
  //Set the Relay pins as an output
  pinMode(D0, OUTPUT); // Relay 1
  pinMode(D1, OUTPUT); // Relay 2
  pinMode(D2, OUTPUT); // Relay 3
  pinMode(D3, OUTPUT); // Relay 4
  //Initialize the Blynk library
  Blynk.begin(auth, ssid, pass, "blynk.cloud", 80);
}

void loop() {
  //Run the Blynk library
  Blynk.run();
}
