Frequently Asked Questions
Arduino Web Editor
Which OS is supported?
The Web Editor is supported on Windows 10, MacOS High Sierra, Ubuntu last LTS version and Chrome OS.
Which browsers are supported?
The Web Editor runs stable on latest versions of Chrome, Firefox, Edge, and Safari.
Which boards can I use in the Web Editor?
You can use all Arduino boards (there’s a complete list in the Help page of the Web Editor).
I am not able to install the plugin...
- Start by following the getting started guide.
- Be sure that you have administrator permission on your machine; if the computer you are using is not your own personal computer, ask your IT administrator for an upgraded profile.
- Sometimes the plugin installation can be blocked by firewall or antiviruses; in the latter case, you can try to add the plugin to your AV whitelist.
I have installed the plugin, but the board is not recognized...
- After installation, you should wait for drivers to be installed.
- Try to avoid USB 3.0, since it has been found that it can cause some issues.
- Remember that third-party boards are not supported in the Web Editor, so they will not be recognized.
- Try to reinstall the plugin and make sure that you give required permissions (sometimes browsers automatically deny hidden pop-ups).
- Make sure you are using Arduino Create in the same browser the plugin is installed.
Web Editor says to install the plugin but I already installed it...
- Check if the plugin is running: you should see the icon in the taskbar and its color should be blue/green. If you don't see the icon, open the plugin by running Arduino Create Agent. If the icon is grey, click on it and then click on Open Plugin.
- Try to reinstall the plugin and check all pop-up boxes for permissions (pop-ups could be hidden by the browser or blocked by antiviruses).
My board is suddenly not detected by the Editor!
- Try to reset the board by pressing the reset button on it while it is connected to the computer.
- Try to clear the cache in your browser.
- Check if the USB cable you are using is working and it is correctly connected to the computer.
My sketch compiles but not uploads or upload button is grayed out...
- Check if the plugin is running (you should see the icon in the taskbar and its color should be blue/green).
- Use Arduino Create in the same browser the plugin is installed.
- Avoid using USB 3.0, since it can cause some issues.
- Check if the plugin has been blocked by firewall or antivirus.
Where are stored the files I see in the Web Editor?
They are stored in the cloud, but you can download them on your computer. After downloading a sketch, the downloaded version will not update if you change the same sketch in the Web Editor.
Arduino IoT Cloud
What devices can I use in IoT Cloud?
Currently, the MKR1000, MKR WiFi 1010 and MKR GSM 1400 boards are supported. In the future, the MKR Vidor 4000 and Arduino Uno WiFi Rev2 will be supported too.
My device can't connect to WiFi or to IoT Cloud...
- Check if your WiFi credentials are correct.
- Check if you have configured the board you are using: you should see it in the Device Manager page (if not, follow the getting started guide).
- Be sure your device has enough power supply; sometimes peripherals attached to the board requires too much power and the board operations get compromised.
- Try to update the WiFi firmware if you have not the latest version installed on your board. You can follow this tutorial for updating the firmware of MKR1000 boards or this tutorial for MKR WiFi 1010 boards.
Is the ESP8266 supported by the IoT Cloud?
No, it isn't. At the moment you can use the ESP8266 in the Desktop Editor only.
