In this video, we will learn how to make a home automation system using the Nodemcu ESP8266 board and the new Blynk application. I used a two-channel relay module for that. You can use any other relay module.
OK, enjoy it now.
Short and sweet tutorial.Only from SriTu tech. If you think this video is good, don't forget to like and comment.

You have created a fantastic video. My question to you is that, is it safe to connect 5V DC to NodeMCU, because as far as I know, NodeMCU works on 3.3V Power supply. Do correct me if I am wrong🙂
