Wiring View and EyeBuild
Stage 2 of every project: the circuit your logic needs, drawn on a breadboard, with a trainer to build it and a camera check for the real thing.
Open it
In the editor, click 2 Wiring in the stage bar at the top (between 1 Logic and 3 App). Nothing to set up: the diagram is drawn from the blocks you already have.
What the diagram shows
- Your board, a breadboard and every part in your project, drawn as real hardware.
- A wire for every pin your blocks use, plus ground and power where a part needs them.
- A resistor in series wherever a part needs one, such as an LED.
- I2C sensors wired to the board’s SDA and SCL pins.
The diagram is drawn for the Arduino Uno, Mega 2560, Nano and ESP32 DevKit. Pick the board in the editor toolbar. For other boards the Wiring view says it can’t draw them yet rather than show a guess.
The wiring check
Before you build anything, the Wiring view looks for problems and lists them:
- Two parts on the same pin.
- A pin the chosen board doesn’t have.
- A part that needs 5 V on a 3.3 V board, or a part whose supply voltage isn’t known.
- On an ESP32, an analog pin that stops working once Wi-Fi connects.
Fix them in Logic (or by dragging a wire, below) and the list updates.
Drag to rewire
Drag the end of a wire to a different pin on the board. The block’s pin setting changes with it, because the wiring and the logic are one project, not two copies. A pin the part can’t use is refused. Undo works as usual, and Reset moves puts every wire back.
Build it myself
Click Build it myself to learn the circuit by building it. The wires disappear and a guide takes you through them one at a time:
- The leg the next wire starts from glows.
- Drop the wire on the hole where it belongs. A wrong hole flashes and you keep your progress.
- After two misses you get a hint; after four, the right hole pulses.
- When every wire is in, the finished diagram comes back.
Building never changes your logic. If the wiring check found problems, the button reads Fix issues to train until they’re fixed.
EyeBuild: check your real board with the camera
Once the parts are on your desk, EyeBuild compares your real breadboard with the diagram and tells you the one thing to fix.
- In the Wiring view, click Check my real board. A panel opens beside the diagram so you can see both.
- Click Start camera and fit the whole board in the frame, or click Check a photo to upload one. Lay the board flat, in good light, with the pin labels readable.
- Click Check my wiring. The answer is Matches your diagram, One thing to fix (with what to change), or I can’t see it clearly yet.
- Turn on Keep watching to re-check every 10 seconds while you move wires. It stops by itself once the board matches.
| Plan | EyeBuild checks |
|---|---|
| Free | 30 a month. The panel shows how many are left this month. |
| Paid plans | Unlimited |
- You need a free account. Signed out, the panel asks you to sign in.
- Each check sends one picture to an AI vision model together with your project’s wiring. The picture is not stored.
- Only checks the AI actually answered count toward the 30. If EyeBuild can’t look right then, it says so.
- It can be wrong. Under each answer, Was this right? lets you tell it.
Next steps
- Connect the board and press Play: Getting Started walks through it.
- Check the pins each part uses on the components page.
- See the same project as Arduino code in Dev mode.
