Blynk IOT ESP32 Home Automation System Manual and IR Remote Control Feedback System




Hey friends in this tutorial I will show you how to make Blynk2.0 ESP32 WiFi, IR Remote and Manual Control Home Automation with Feedback System.

I will also show you how to configure and Reset WiFi connection of ESP32 with Blynk IOT 2.0 Application.

No Hard Coding required for WiFi Network Connection.

You will be able to control your Appliances, Devices with Smartphone Blynk application from any where around world and Manual Switches as well.

I have designed PCB For this project which makes this project very simple, compact and easy to use and install. This PCB can be used for multiple projects with ESP32 Nodemcu Board.
