Introduction
In this Article, We Try To Build An ESP32-based Home Automation With the new Blynk App.We control the home application LIke TV,FAN,LIGHT,ETC with the mobile app and Blynk webserver.

Component’s Overview
ESP32 Board
- The ESP32 Board Is Integrated with Wi-Fi And Dual-Core, Low Power Bluetooth, Low Power Consumption, and High performance.
- ESP32 Is a small board With many pins available To Connect to the input and output Devices.
- Compared to the Esp8266 Board, so many Analog pins are Available On the ESP32 Board and it Takes Low Power.
Relay Module
2 Channel Module is Used A wide range such as Arduino,PIC,Raspberry.
1 Channel Relay Module But In This Project I Used 2 Channel Module
Features
- Operating Voltage: 5V
- Max Current : 20mA
- Relay Contact Current Capacity at AC250V: 10A
- Relay Contact Current Capacity at DC5V: 10A
Circuit Diagram
In this Circuit Diagram We conected the 2 channel moduel to Pin Number D12 & D14 on ESP32 Board.
Blynk App Setup
Create The Template
Now, We select the Switch, edit the names LIGHT1 & LIGHT2, and select the Virtual Pin V0 & V1.
Now App will be ready then copy the token ID and paste a Code.

Project Explanation
Now the System will Power Up and Reday to used the projects.the webserver and mobile app also conected to the ESP32 Board.
When we click the On/Off Button then AC Blub will turn On/off.
Now the Both Switch Will On And Is display on Conduction in Blynk Mobile App As Well As Webserver.
