ESP8266 NodeMCU WebServer Statik Ip

It is made to control led remotely with Web Server.I used ESP8266 NodeMCU, but it can be used in other versions.

Arduino IDE Settings

I assume you have Arduino IDE on your system. However, the ESP8266 we will be using does not come in the standard installation of the IDE, so we will have to do some additional processing.

Let's add the following address to the Additional Circuit Boards Manager URLs section from the File>Preferences menu.

http://arduino.esp8266.com/stable/package_esp8266com_index.json

Then find and install ESP8266 from Tools>Card>Card Manager:

Next we need to add ESP8266WebServer, the only library we will use. Draft > add library > manage libraries

Usage

We load the Wi-Fi library

#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>

Enter the local network information

You need to modify the following two variables with your network credentials, so that your ESP8266 can establish a connection with your router.

const char* ssid = "REPLACE_WITH_YOUR_SSID"; 
const char* password = "REPLACE_WITH_YOUR_PASSWORD";

Setting ESP8266 Static IP Address

IPAddress gateway(192, 168, 1, 1);                 // Default Gateway
IPAddress local_IP(192, 168, 1, 37);             // Static IP Address for ESP8266
IPAddress subnet(255, 255, 0, 0);                // Subnet Mask

Important: You need to use an available IP address in your local network and the corresponding gateway.

Command required to connect to your local network

WiFi.begin(ssid, password);

We check that the connection is established

while (WiFi.status() != WL_CONNECTED) {
  delay(1000);
  Serial.print("."); //"." on the screen until the connection is established. We get it out.(Loading)
  }

Finding the ESP IP Address

Press the ESP8266 RESET button, and it will output the ESP IP address on the Serial Monitor

Copy that IP address, because you need it to access the web server.

Accessing the Web Server

Open your browser, type the ESP IP address, and you’ll see the following page. This page is sent by the ESP8266 when you make a request on the ESP IP address.
