Interfacing of blynk app to arduino uno through ESP8266 wifi module

hellow
i am making a home automation kind of project with the help of blynk but i am not able to understand that how to send and receive the data using blynk app please anyone helpā€¦!
waiting for your responsesā€¦
thank you.:smiley:

also i am not able to understand that which example must be considered for starting the projectā€¦!
need guidanceā€¦

Welcome to Blynkā€¦ thatā€™s what all those Documents, Help Centers and Sketch Builders are for at the top right of this pageā€¦ Guidance :wink:

http://examples.blynk.cc/?board=Arduino%20Uno&shield=ESP8266%20WiFi%20Shield&example=GettingStarted%2FBlynkBlink

Also use the search option for this forum (the magnifying glass icon, also in the upper right of this page). Try words like Arduino, UNO and ESP8266ā€¦ you will find many others asking the exact same questions, and eventually learning how it is done.

thank you sir,
i have already done these steps but still confused about the connection and and how the thins are going and also some errors are encountering

Arduino: 1.6.11 (Windows 7), Board: "Arduino Duemilanove or Diecimila, ATmega328"

WARNING: Category '' in library UIPEthernet is not valid. Setting to 'Uncategorized'
C:\Users\Soni\Desktop\community_test\community_test.ino:4:25: fatal error: ESP8266_Lib.h: No such file or directory

 #include <ESP8266_Lib.h>

                         ^

compilation terminated.

exit status 1
Error compiling for board Arduino Duemilanove or Diecimila.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

what should i do in this situationā€¦??

i have taken code from blynk script builder.

Start by learning how to install the ESP8266 libraries into Arduino IDE.
