Before we can use the NodeMCU board we need to install the ESP8266 board and it's library on the Arduino IDE in order to use the WiFi functionality. This will be done as follows:

Open the Arduino IDE software on your computer. Go to File> Preferences

Add the link: to the “Additional Boards Manager URLs” field as shown in the figure below. Then, click the “OK” button:

Open the "Boards Manager" and go to Tools > Board > Boards Manager

Search for ESP8266 and press install button for the “ESP8266 by ESP8266 Community“:

In a few second, you should be able to see the following:
