We all have switched on lights,fan and other appliances using Bluetooth as a for low range applications. Now we are going to look over controlling appliances using WiFi. Now we are restricted here to local WiFi only but you can host your IP on any site like 000webhost etc. to control it from anywhere from the world.Here we are going to learn that.
We would mainly understand here the working of the WiFi to switch on off appliances and the working of relay that we are going to use. NodeMCU will be here the brains of the organisations.It has inbuild WiFi capabilities. You can learn more about it in any instructables or YouTube video.So I’m not going into here its hardware here.”
