Sketch example on how to make chinese Arduino UNO R3 + ESP8266 board to communicate with its ESP module.
The purpose of this repo is to show how can we make our program stored on ATMega328 have access to the Internet and/or provide its state to the Internel with ability to operate with that state from external devices.
The code from WiFi_AT folder goes to ATMega, the code from WiFi_ESP goes to ESP8266.
