In today’s Tutorial we will learn About Hosting webserver on Your ESP8266 board in just few minutes.
You have to follow these simple steps.
Components Required :-
1- ESP8266
2- Type B Cable
STEP 1 – Open Arduino IDE
Install the ESP8266 Board in your Arduino IDE , If you haven’t install yet . Just click on this link and you found installation process for ESP8266 – https://elconics.com/getting-started-withesp32/
just go here –
After installation select the correct COM port and Board almost 90% of your task done.
STEP 2 – Select board and comport to Upload the code to ESP8266
Select com port
If you get Garbage value then Select baud rate written on code which is- 115200

}Now SET your SSID(Your WIFI name) and Password(Your WIFI password) upload this code in your esp8266 after uploading the code open serial Monitor Copy the IP address paste it in your browser.
Make sure your ESP and Your phone browser should connected with same Wi-Fi
Now you will see one webpage will open with buttons Webpage task is done
Now connect RGB led or and LED at PIN 1,2,3 I am using CC-RGB Led
