Controlling 220V Light Bulb Through Wi-Fi with NodeMCU

Controlling 220V Light Bulb Through

WiFi with NodeMCU

Purpose: 
       This technology that cooperates with the internet is easy control any electronic devices in order to gain us more advantages on time and money. This project can applies to many factors in our lives like At Home, Hotel, Factory, Construction site…. Furthermore this project have a wide range of usage depend on the requirement of the modern technology in the 21 Century of Human!!

   1. Description 

         In this project we will show you a I <3 FE production using 220V light bulb. All bulb in each letter are parallel which you can control from anywhere you are using a local Wi-Fi with NodeMCU. The range of it is infinite. Either you in another country or another continent you can control them if you have the internet. 

   2. Detail

          This small project required using NodeMCU to connect to a specific Wi-Fi which we will need it to be near NodeMCU in order to control the bulb. Using NodeMCU we will connect it to the Blynk app which we will control it from anywhere from the world. We will also be using the Arduino IDE to code the NodeMCU. Phone will be the most significant role of all for this project because we will be controlling NodeMCU from our Phone (IOS or Android).
