Hello friends, I hope you all are doing great. Today, we will create a web server with ESP8266 microcontroller to control the activation of an LED. The goal is to understand how the ESP8266 connects to a WiFi network, how it sets up a web server, and how it is possible to exchange information between the browser and the esp8266. Components Required 1x Computer/notebook with Arduino 1x Mini-USB cable. 1x NodeMCU (ESP8266 Breakout Board) Internet Browser (Chrome, Firefox, IE…) ESP8266 Libraries for Arduino IDE For this project, we will use two libraries: ESP8266WiFi : This library carries all the functions necessary for the ESP8266 to connect to a wifi network. ESPAsyncWebServer : This library carries the functions needed to create and manage an EB server. Creating the code We can divide the ...
