ESP32 Access point (AP) and Station web server with HTML using Arduino IDE

ESP32, ,

In this tutorial we are making ESP32 as both Station and Access point and web server. We have seen how to connect to WiFi Router and make web server in previous post.

What you will Learn?

  1. Making ESP32 as Access Point
  2. ESP32 as Station
  3. ESP32 as both Station and Access Point at the same time
  4. ESP32 as web server with HTML web page
  5. Using Java Scripts in ESP32
  6. Using CSS in ESP32

A Web server is a program that uses HTTP (Hypertext Transfer Protocol) to serve the files that form Web pages to users, in response to their requests, which are forwarded by their computers’ HTTP clients.

ESP8266 Arduino WiFi Web Server LED on off control

ESP8266, , ,

In this tutorial, I am going to tell you about controlling LED using web server over WiFi using ESP8266 module or NodeMCU. So let’s start. In this tutorial we are using onboard LED of NodeMCU. If you are using different hardware you can connect led to GPIO2 or make changes in code as per your connection.

There are many ways to control LED over WiFi. We will go from basic to advance method of controlling LED using WiFi.

ESP8266 mDNS

ESP8266, , ,

This tutorial explains how to Multicast DNS using ESP8266? In networking world it is difficult to remember ip address of each website and computer, to solve this problem Domain Name System (DNS) is used to make human understandable names. In ESP8266 when using ESP as web server, It is difficult to remember ip address of ESP8266 and also it is difficult to identify ip address of ESP in DHCP mode. i.e. WiFi router assigns IP address to ESP8266. Most ESP8266 application doesn’t have display interface and they are not easy to access to know its IP address. To overcome this problem mDNS is used. Continue reading ESP8266 mDNS →
