eabulislam Staff asked 6 years ago how to change ip address/on or off push button press.
actually i want to control led on off press push button when not present wifi device .
when press push button change link ip
192.168.0.1/light1on
or
192.168.0.1/light1onoff
here my code
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
WiFiServer server(80); //Initialize the server on Port 80
//io output pin configaration
int fan = 5;
int light1=4;
int light2=0;
int light3=2;
int pwmValue;
