Home Automation Using NodeMcu | IOT Based System | Control Appliances From Any Part Of The World

In this loT based project, we will learn how to do Home automation using NodeMCU and Blynk App. This is a simple but useful home automation project with Nodemcu and a relay module where we can control home appliances securely from the smartphone. During the video, I have shared the Circuit Diagram, Blynk example library for this internet of things project.

**You have to install the Blynk library before uploading the sketch. I have shown all the details in the video.

In this video, I have shown step by step how to download and use the Blynk app for this smart house project. I have also shared circuit diagram which help you to connect the 4-channel or 8-channel relay module with the Esp8266 NodeMcu Board.
