From Idea to a Real Board, in One Tab

Design on the canvas, read the real Arduino code beside it, run it on a real board over USB, and build with friends — without leaving the browser

ArduinoStudio canvas and live Arduino code in one browser tab — The real editor: the Logic canvas with its Arduino code open below it.

HardwareUSB directRun it on a real Arduino from Chrome or Edge, with nothing to install. On an Uno R3, Nano or Mega 2560 the tab even installs the firmware.

Live preview · no account, no board

Press Play. Then plug in your board.

This is the ArduinoStudio editor in miniature, running a real project: blink the LED on pin 13. Press Play, change a Wait and watch the Arduino code change with it, add a button, then flip through Logic, Wiring and App. When it works here, the same blocks run on an Uno, Nano or Mega from Chrome or Edge, and pin 13 already has a small LED on the board.

Change a delay here and its Wait block updates. In the editor you can also change pins, HIGH/LOW, loop counts, messages and thresholds, and type new lines like delay(500); to add blocks. Loops and Checks are added on the canvas.

On your desk

What the same project does on a real Uno.

Pin 13 drives the small LED marked L on the board, so this project needs no extra parts.

Now run it on a real Arduino

It works here. Next, make a real board do it.

I have a board

USB direct works in Chrome and Edge on a computer, and on Chromebooks.

Which board do you have?

Parts: none. Pin 13 drives the small LED marked L on an Uno R3, Nano or Mega 2560.

Sign in, and a new project opens with this idea in the AI Builder. Review the plan and press Apply.
Plug the board into this computer with a USB data cable, press USB direct in the editor toolbar, then Connect. Your browser asks which port to use: pick your Arduino (it may be listed as “USB Serial”).
On an Uno R3, Nano or Mega 2560, the editor offers to upload ArduinoStudio-FW the first time. It is one upload per board, and it replaces the sketch already on the board. Then press Play.

Free account. The AI Builder makes this project from its description; you review the plan before anything changes.

Your project runs on the board while this tab stays open. To keep a program on the board by itself, download the .ino and upload it with the Arduino IDE.

Chain blocks into sequences: 21 real parts plus Loop, Check, Wait and Message. Press Play with no board and the simulator runs it: the running block lights up, waits count down, and the Virtual Board shows every pin your project uses, with buttons you can tap and sensor sliders you can drag to test your Checks.
How the simulator works →
Your blocks draw their own breadboard diagram, with resistors where they belong, and pin conflicts are flagged before you build. Move a wire and the project changes with it. In the editor, Build it myself walks you through it wire by wire, and EyeBuild checks your real breadboard through your camera. Diagrams are drawn for the Uno, Mega 2560, Nano and ESP32 DevKit.
About the wiring view →
Lay out buttons, sliders, indicators, text, shapes, emojis and images, and preview them at phone size. A button runs your sequences on click, double-click or hold. To drive a real board from the panel, the editor uses the desktop Bridge app; over USB direct a press runs the simulator, and indicators and sliders always show the simulator.
About the App stage →
Your blocks are a real Arduino sketch that updates on every change. Change a pin or a delay in the code and the block follows; Loops and Checks are added on the canvas. Copy it, or download the .ino and upload it yourself with the Arduino IDE.
ComingDeeper full-code editing.
What syncs →

A preview built for this page. It follows the editor’s own run timing, Check rules and Arduino code for these blocks. The editor itself has 25 blocks, the AI Builder, sharing and collaboration.

The Core Features, Shown in the Real Editor

Screenshots from the editor itself. Each one shows a feature, explains how it works and lists what you can do with it. All 26 features →

1 · Logic

Simulator

Press Play with no board plugged in and your project runs in the browser. The block that is running lights up, a Wait counts down, a Loop counts its passes, and the Virtual Board panel shows each pin switching on and off. Tap a button or drag a sensor reading on that panel to test a Check.

What you can do

Try a project before you own a single part
Tap a virtual button, or drag a knob or light reading, to test a Check
Run several sequences at once and watch each one step through

Fully simulated: Standard LED, Servo, Button, Photoresistor, Switch and Potentiometer. Other blocks are limited or don’t simulate yet, and it shows pins, not voltages or current.

Start

AI Builder

Describe a project in your own words and the AI Builder plans it: the logic blocks and their settings, a control panel and a README. It shows you the plan and changes nothing until you press Apply. On a project you already have, it edits what is there.

What you can do

Start a new project from one sentence
Ask for a change to a project you already have, like adding a button
Check every planned block and setting before you apply it

You need an account. It works from text, and the wiring diagram draws itself from the blocks it places.

Wiring diagram

The Wiring stage for the Traffic Light project: an Arduino Uno wired to three LEDs and their resistors on a breadboard, a Circuit ready banner reading 6 of 6 connections ready, and the Build it myself and Check my real board buttons. — The Traffic Light circuit, drawn from its blocks: 6 of 6 connections ready.

Switch to stage 2 and your blocks draw their own breadboard diagram: the board, the breadboard, every part, and resistors where they belong. It flags pin conflicts and power problems before you build. Drag a wire end to another pin and the block’s pin setting changes with it.

What you can do

Build from a diagram that always matches your project
Move a part to another pin by dragging its wire
Place the wires one at a time with Build it myself, with a hint after a few misses

Diagrams are drawn for the Uno, Mega 2560, Nano and ESP32 DevKit.

EyeBuild: check your real boardNew

The EyeBuild panel open beside the wiring diagram, before the camera starts: a short explanation, an empty camera area asking for the board to lie flat in good light, the Start camera and Check a photo buttons, the list of 6 wires it checks, and a note that photos go to the AI provider and are never saved. — EyeBuild opens beside the diagram and checks the 6 wires this project needs.

Point your camera at your breadboard, or upload a photo. EyeBuild compares it with your wiring diagram and names the one thing to fix. Turn on Keep watching and it checks again every 10 seconds while you move wires.

What you can do

Find a wiring mistake without tracing every wire yourself
Check a photo instead of using the live camera
Leave Keep watching on while you rewire

You need an account, and it works on the boards that have a wiring diagram. Each photo goes to an AI provider to be checked and is never saved.

3 · App

Control panel builder

The App stage of an automatic door project: the Elements list with an Open Door button set to run Sequence #1 on click and a Door Status element, the canvas with both elements, and the Function tab where On click runs Sequence #1. — An Open Door button set to run Sequence #1 on click.

Stage 3 is where you design your own control panel: buttons, sliders, indicators, text, shapes, emojis and images, laid out the way you want. Choose which sequences a button, shape, text or image runs on click, double-click or hold. Preview the panel at desktop or phone size, then press Play to use it.

What you can do

Make a button that runs a sequence when you press it
Light an indicator from a pin while the project runs in the simulator
See how the panel looks on a phone before you share it

With USB direct, a press runs your sequences in the simulator. To drive a real board from the panel, use the Bridge desktop app.

Arduino code

Edit the code, the blocks followNew

Open the Arduino code view and your blocks become a real Arduino C++ sketch, docked under the canvas and updated on every change. It works the other way too: change a pin, a delay or a loop count in the code and that block updates as you type. Type a new line such as delay(500); and a new block appears.

What you can do

Select a block to light up its lines, or click a line to find its block
Delete a block’s lines to remove the block
Copy the sketch, or download it as an .ino for the Arduino IDE

Loops and Checks are still added on the canvas. The app doesn’t upload your sketch; to run the code itself, open the .ino in the Arduino IDE.

Hardware

USB direct

Plug your Arduino into your computer, open the project in Chrome or Edge, and connect with USB direct: the browser drives the board over USB, with nothing to install. If an Uno R3, Nano or Mega 2560 doesn’t have the firmware yet, the setup wizard installs it from the tab. Your project runs on the board while it stays plugged into the open tab.

What you can do

Drive LEDs and servos, and read buttons, switches, knobs and light sensors
Get a new Uno R3, Nano or Mega 2560 ready without the Arduino IDE
Switch back to the simulator any time, with no board

USB direct works on a computer and runs the Standard LED, Servo, Button, Photoresistor, Switch and Potentiometer blocks. For Firefox or Safari, or blocks such as the RGB LED, DC motor and relay, use the Bridge desktop app.
