How to install Nodemcu board in the Arduino ide

 One of the most common questions I get from someone who is beginning to learn about the Nodemcu(esp8266) board is "How do I install the board in the arduino IDE?" That's because you can't directly write an esp8266 code in the arduino IDE. Arduino IDE, by default is set up to program an arduino board only. To program a different compatible board, you need to install it in the arduino IDE.
So here I present to you, a step by step process to install the nodemcu board or any board in general, in the arduino IDE.

Step 1:

Make sure you have a good internet connection.

Open the IDE and click on File -> Preferences

A new window will pop up. In the Additional Boards Manager URLs type the following:

http://arduino.esp8266.com/stable/package_esp8266com_index.json

After typing, click on "Ok"

 

Step 2:

Go to Tools -> Board -> Board Manager

Another window will pop up. Wait for it to load everything.

Type "esp8266" in the search box

Install the one that says "esp8266 by esp8266 community"

Installing libraries in an easy way

Another common confusion occurs while installing libraries. If you search online, most websites tell you to download them from github and move the file to a folder in the arduino's files. But there is a simpler way that is straightforward.

In the arduino IDE, go to sketch -> Include library -> Manage Libraries

A new window will pop up. In the search box, type the library name (for example, "adafruit am radio" or "blynk") and click on install. That's all!

Hope this guide got rid of the confusions you had. Good luck on your next IOT project!
