Building the board…

01Workbench

Wire it up on the workbench

Put a board on the bench, add sensors, motors and displays, run jumper wires from pin to pin and press Run. Guided missions walk you through real circuits; Free build lets you wire anything.

  • Missions

    Step-by-step builds — blink an LED, read a sensor, drive a motor.

  • Real wiring

    Click a pin, click another: the bench checks every connection before power-up.

  • Room to work

    Press Full screen in the workbench toolbar to give the bench the whole display.

03Quiz & assembly

Now try it with your own hands

Reading about a board is one thing; finding the parts yourself is what makes it stick. Both exercises run on the 3D model at the top of the page and work for every board.

Quiz · about a minute

Find the part

We name a part — you find it on the model and click it. Rotate the board, zoom in and flip it over, just like the real thing.

  1. 1

    Read the question. “Find the microcontroller — the brain of the board.”

  2. 2

    Click the part. Not sure? Take a hint, or skip and see the answer.

  3. 3

    See your score. Only first-try answers without a hint count.

Assembly · a few minutes

Take it apart, put it back together

The board comes apart into a tray of parts on the bench. Put every chip, connector and header back where it belongs and solder it down.

  1. 1

    Pick a part from the tray. Chips, connectors, headers, buttons.

  2. 2

    Place it on its footprint. The pads on the bare board show where it goes.

  3. 3

    Solder it in. When the last joint is done, the board is whole again.

All eight, side by side

The numbers that decide which board fits a project. Click a row to put that board on the bench — the lesson switches to it too.

Prices are typical street prices and vary by seller. “Logic” is the voltage of the I/O pins — never feed 5 V into a 3.3 V board.
