Home automation using NodeMCU and Blynk App - IOT based Project

In this IoT 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, Arduino sketch, Blynk example library for this internet of things project.

Download the Code: https://drive.google.com/drive/folder...
**You have to install the Blynk library before uploading the sketch. I have shown all the details in the video.

Required components for this WiFi relay module:
1. NodeMCU board
2. Relay Module 5volt
3. 5 volt DC supply

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 NodeMCU pinout details, which help you to connect the 4-channel or 6-channel relay module with the esp8266 Nodemcu board.

After watching the complete video you can easily design this low-cost smart home device and control the relay module with wifi.

thanks for watching
