How to configure ESP8266 with Arduino - Arduino WiFi Shield

Yesterday we knew how to add the ESP8266 board to Arduino IDE.

Today, we are examining how to configure it using Arduino UNO board.

ESP8266 is low cost Arduino compatible development board. It can act as a standalone board that runs Arduino code just as any Arduino compatible board.

It can also be thought of as an Arduino Wi-Fi shield. In this concept, you can configure it and then use it as Wi-Fi shield that serially connects to Arduino.

In the previous post, we learned how to configure connect and program the ESP8266 using USB to TTL converter that has 3.3v selector switch (FOCA).

We can also configure the ESP8266 using Arduino UNO board as we’ll see in this post.
