“This project mainly focuses on creating an ESP8266 based WiFi shield for Arduino UNO.
This shield can be used to program ESP8266 in two modes.
Either through AT commands or directly through the Arduino IDE.
What is ESP8266?The ESP8266 is a low-cost Wi-Fi microchip with full TCP/IP stack and microcontroller capability produced by the manufacturer Espressif Systems in Shanghai, China.
The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each ESP8266 module comes pre-programmed with an AT the command set firmware, meaning, you can simply hook this up to your Arduino device.”
