Arduino Web Editor Guide

The following article covers the whole Arduino Web Editor.

Your learn the advantages and disadvantages of the Arduino Web Editor before we see how to sign up for the Editor.

After we get an overview of the whole Web Editor I show you how to flash a sketch from the Arduino Web Editor to your Arduino board and how you can import sketches and projects from your local computer to the Web platform.

What is the Arduino Web Editor?

The Arduino Web Editor is the whole Arduino Desktop IDE online in a web browser. With the help of the Arduino Web Editor you are able to create and document your Arduino projects, create sketches, flash sketches onto your Arduino board and share your work with your friends.

Advantages / Disadvantages using the Arduino Web Editor in comparison to the Arduino IDE


  • Save your sketches in the Arduino cloud to access them anytime and everywhere. Also your sketches are protected against data loss.
  • You do not have to update your IDE because the Arduino Web Editor will always run the most up-to-date version of the IDE.
  • You can easy share your projects with your friends or colleges.


  • You only can work with Arduino boards in the Arduino Web Editor. Most of the time I use boards based on the ESP8266 like the NodeMCU and I can not flash a sketch to this board. Therefore I do not use the Arduino Web Editor.
  • A plotter like in the Arduino Desktop IDE is not available in the Arduino Web Editor

Sign Up and Log In to the Arduino Web Editor

OK now we want use the Arduino Web Editor. The following chapter will be a tutorial how to sign up for the Arduino Web Editor and how to use the IDE.
First visit the homepage of the Arduino Web Editor.

If you already have an account you can log in on the left side. If you want to sign up with your google account, use the button below. Also you can create a new account clicking on the right avatar. I use the option to sign in with google. You have to choose a username and confirm the policies.

Arduino Web Editor Login

After the Arduino Web Editor is loaded you can choose if you want to take a tour to view the main features.

Arduino Web Editor Startup

If you click “No, thanks” you will see the overview of the Arduino Web Editor.

Microcontroller Datasheet eBook

The 35 pages Microcontroller Datasheet Playbook contains the most useful information of 14 Arduino, ESP8266 and ESP32 microcontroller boards.

Overview of the Arduino Web Editor

The IDE is divided into 3 main columns. We go into the first column in detail because the first column is the main control area for the Web IDE. The second column is directly dependent on the selection of the first column and acts like a side panel. The third column is the code area where you write your script, verify the script if everything is coded right and finally upload the sketch to your Arduino board.

Arduino Web Editor IDE Overview

The Sketchbook is your default view if you start the Arduino Web Editor. On the second column you have different options to do:

  • Create a new sketch
  • Create a new folder to organize your sketches and projects
  • Import sketches
  • Select a sketch to work on it in the third column
  • Search for a sketchbook

In this section you can select example sketches to quickly test a board or to see if you can adapt some code parts to your own sketch. Most of the examples are the same as the Arduino Desktop IDE.

Of course you can import different libraries to provide extra functionalities. The process is the same as in the Arduino Desktop IDE. For most and for all standard or most used component you will find the corresponding library in the manual of the component.

Arduino Web Editor Libraries

Serial Monitor
If no board is connected, the Serial Monitor will be greyed out and unavailable. A plotter like in the Arduino Desktop IDE is not available in the Arduino Web Editor

In the second tab of the help section you find different tutorials to get started with the IDE. In the third tab you find a glossary for all names that you might be unfamiliar with.

In the preferences you see how much space you are currently using. Because the sketches and projects are saved in the Arduino cloud the space is limited to 100 sketches and 100 MB. In my opinion are 100 sketches a good amount.
Also you are able to edit the front size of the editor and the editor theme if you prefer a dark theme over a light theme. Looks a bit nerdy the dark theme right ;)?
There are although several check boxes in the preferences:

  1. Save when verifying and uploading. Should be enabled that you make sure what code is on your Arduino board.
  2. Enable Autosave. This option should although be enabled because I really lost time because I programmed till the last minute and then I quickly shut everything down without remembering to save my sketches.
  3. Always show output panel. In my case I use the output panel a lot and therefore I always let this option checked. If you do not use the output panel, you can disable this option.

Last there are two advanced option which I did not touch and therefore these two options are unchecked.

Upload a sketch to your Arduino board

If you want to upload your sketch to one of your Arduino boards you first have to install a plugin so that your firewall is not blocking the traffic. You can download the plugin for Mac, Windows or Linux from this URL.

Arduino Web Editor Plugin Installation 1

The file you have downloaded should be like ArduinoCreateAgent-1.1-windows-installer-chrome.exe. Double click on the exe file to install the plugin. I suggest to use the chrome browser together with the plugin because this combination runs very stable. After you successfully installed the plugin, your operation system is asking you if you want to install the corresponding drivers: VBoxManage setextradata “Ubuntu” VBoxInternal2/EfiGraphicsResolution X

Click Yes to install the drivers. Now you have a new symbol in your taskbar. If you look back into your browser, the Arduino Create platform is searching for the installed plugin.

Arduino Web Editor Plugin Installation 3

After 1-2 minutes the platform found the plugin. Click Next to return to the Arduino Web Editor. In the Arduino Web Editor select an example sketch to test the connection between the IDE and your local Arduino board.

Arduino Web Editor Plugin Installation 4
After you select for example the blink sketch you have to select your corresponding board and the connected port (1).

Arduino Web Editor Plugin Installation 6

After you selected board and port you can upload your script (2).


Import your sketch from the Arduino IDE
Now if you want to change coding from Arduino Desktop IDE to the Arduino Web Editor, there is a very useful import function. You only have to select Sketchbook from the first column and then Import on the second column.

Arduino Web Editor Import Sketch

You can import 3 different types

  1. Single sketches in .ino, .pde and .zip format.
  2. Libraries in .zip format.
  3. Zipped folders containing sketches and libraries. Make sure your libraries are in a folder called ‘libraries’. Be sure not to mix sketches and libraries in the same folder.


As said in the first section of this article I like to use different bards. Most of the time I use NodeMCU boards and these boards are not compatible with the Arduino Web Editor. Therefore I am using the local Arduino IDE for all of my projects. Do you prefer the Arduino Web Editor over the Arduino Desktop IDE? If so, why and do you like to share your over the Web Editor? Feel free to answer in the comments below.
I also wrote a tutorial for the Arduino Desktop IDE, which you find here.
