The WiringДЇor this project, weвЂ™ll be using the Arduino to communicate with the ESP8266, which means weвЂ™ll be making use of the transmitting and receiving pins to communicate with the Arduino Wi-Fi module. With that in mind, weвЂ™ll wire up the project first, and then discuss the commands to connect it to Wi-Fi. Your ESP8266 module should come with the proper firmware already flashed to it, which will make the process of connecting it to your Wi-Fi network relatively simple. While there are many Arduino Wi-Fi projects that use a variety of methods to connect to the internet, weвЂ™re going to use an Arduino Wi-Fi module to add Wi-Fi support to a board that doesnвЂ™t already have it. This will make this guide a little different than typical Arduino guides, and weвЂ™ll learn more about the Arduino IDE and the tools it contains.

These microcontrollers can be flashed with a variety of custom firmware that give you a ton of power over how to connect to the internet.ДЇor this guide, weвЂ™re going to keep things as simple as possible (Wi-Fi connections can get very complicated, very quickly) and simply show how to send commands to your ESP8266 that will connect it to your Wi-Fi network. Barring that, the easiest way to add Wi-Fi to Arduino projects is with an Arduino Wi-Fi module like the ESP8266. You can still find some Arduino Wi-fi shields around, although the product has been officially retired. However, most Arduino boards do not, so if you want to connect them to the internet, youвЂ™ll need a separate Arduino Wi-Fi module. Some Arduino boards like the Arduino Uno WiFi have Wi-Fi capabilities out of the box. There are several ways to add Wi-Fi to an Arduino project and depending on your needs, you might not need a separate board at all. In this guide, weвЂ™ll show you how to wire up a Wi-Fi module and instruct it to connect to Wi-Fi. If you want to add Wi-Fi to Arduino projects, you can do so with an Arduino Wi-Fi module, a Wi-Fi shield, or in some cases even an Arduino board that comes with Wi-Fi built in.

Most of the devices you own can connect to Wi-Fi, but your Arduino sits on its lonesome.
