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.
Press Play. No board needed: the simulator runs your blocks right here.

// Generated by ArduinoStudio. // Project: Blink // Board: uno // // Edit freely — this is yours. void run_Sequence_1(); void setup() { pinMode(13, OUTPUT); } void loop() { run_Sequence_1(); } void run_Sequence_1() { digitalWrite(13, HIGH); delay(); digitalWrite(13, LOW); delay(); }
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.
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.

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.
Fully simulated today: Standard LED, Servo, Button, Photoresistor, Switch and Potentiometer. The rest run partly, or not yet, in the simulator. See where every block runs →

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.

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
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
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.

Control panel builder
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.

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.

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.
Learn more about USB direct →Together
Build it togetherNew
Invite a friend by email, or send an invite link, as an editor or a viewer. The project appears in their Shared with me tab, you see who else has it open, and changes sync every few seconds.
What you can do
- Build one project with a friend or a classmate
- Send a view link to show your work without letting anyone change it
- See who else has the project open
Joining needs an account. There are no live cursors, so take turns on the same block.
