Smart Home Using Amazon Alexa

The Basic idea behind this project is to control an electronic appliance using Amazon Alexa or through its app from anywhere in the world. We will be using a Node MCU V1.0 for this. All the code will be on my Github Page. If at any point you don’t understand a step feel free to comment down below and I shall respond to it at the earliest. All Credits for the servers as well as the code goes to kakopappa( I have modified the code to control 4 Relays for the purpose of this tutorial. Well, Lets get started!
Note: This tutorial assumes that you have some knowledge about Arduino IDE and Node MCU.
