Arduino on Chromebook, no installer needed
ChromeOS supports Web Serial natively. Plug in a USB cable, open the editor in Chrome, and your project drives the real board.
Connect through Chrome
Chrome on ChromeOS includes Web Serial. Open the editor, choose USB direct, and select the board in the browser port dialog. A USB data cable and permission to access serial devices are required.
Prepare a classroom Chromebook
Try your lesson on a managed student device before class. Confirm the editor and sign-in load, USB serial access is allowed, and the board completes its first firmware setup.
Start with an LED project
Use a built-in LED to introduce sequences, waits, and loops without extra wiring. Add a button, servo, or light sensor as students learn how inputs and outputs work.
See it run
The editor is the real product — this opens the live demo on a working project. No account, nothing to install.
See it run — no account neededGuided lessons, class codes, and a teacher dashboard for younger learners.
Quick answers
Does Web Serial really work on ChromeOS?
Yes. Chrome on ChromeOS supports Web Serial, which lets the editor request access to a USB serial port. Managed-device policies can restrict that access, so test a student device before planning a hardware lesson.
Which blocks run on a Chromebook?
Over USB direct, the Standard LED, Servo, Button, Switch, Potentiometer and Photoresistor blocks run on a real board. Most other blocks, such as the RGB LED, DC motor, relay and several sensors, need the ArduinoStudio Bridge desktop app, which is made for Windows, macOS and Linux, not ChromeOS. A few blocks don’t work properly on a real board yet.
What boards work?
Arduino Uno, Nano and Mega, including clones with a CH340 USB chip. The browser asks you to pick the port. The editor identifies the board from its USB ID, and when a clone chip could be several boards, it asks which one you have.
What should school IT check?
Check that students can reach the website, app, sign-in flow, and required services, and that the device policy allows the app to request serial ports. Test the full connect-and-run flow on the same managed devices students will use.
Is there a classroom-specific tier?
CHIPS provides a separate classroom experience with guided lessons and class codes for younger learners. Open the CHIPS classroom link to review its teacher setup and available plans.
