If you create an Arduino container in goormIDE, you can connect Arduino to your PC, Also, you can build and upload to the container directly.
The following instructions describe how to install goormduino and connect goormIDE, PC, and Arduino.
Here's the setting guide for chromebook and a regular PC.

Installation process for Chromebook

  1. 1.
    Chrome OS can use Chrome App, so install it from the link. (install link)
  2. 2.
    Once installed, you will see the phrase "It is already installed in your browser."

Installation process for a regular PC

  1. 1.
    Download the (download link)
  2. 2.
    Access to chrome://extensions/
  3. 3.
    Turn on the developer mode on the top-right corner.
  4. 4.
    Unzip the and click the "load unpacked" at the top-left corner to upload.
  5. 5.
    Click Run
Once goormduino is running, you can connect to goormIDE now. Copy the ID starting with ebm ~ shown on the screen above,
Click the Goormduino on toolbar.
In goormduino window, paste the Chrome Extension ID and press the connect button.
Then, you can see a list of boards connected to your computer.

Practice: Upload, Serial Connection

Once you have chosen your board, let's put the code in order. Modification --> build --> upload.
Let's edit the Arduino Sketch code. However, be sure to include #include <Arduino.h> . (The header file required for the build.)
If you finished editing the code, let's build. Keep in mind that the first build after creating a container could be slow.
Did you finish the build? Let's upload!
Once uploaded successfully, you can see the message below.
upload complete!
If it is stuck here,
Start uploading...
something may have gone wrong with the board type or the board itself. Please check one more time.
Serial communication is available via the [Serial Console] on the bottom tab. After setting the board and baud rate (it is set to 9600 in the above screen), press the serial connection button to connect, send and receive various data.
