How To Play Your Biscuits

Start with an empty breadboard and build your biscuit collection: place biscuits, wire them up, and save a snapshot of your setup.

Next time you open Lab Kit, load your snapshot so your virtual breadboard matches your real one, then tap the biscuit panels to play with each module.

If a Biscuit shows There's a Bug on your Breadboard or a Biscuit hint, become a circuit detective and compare your real breadboard with the diagram until every connection matches.

Automation Routine Add blocks, watch live values, then run or step through.
Run in Browser Edit, simulate, and save the full routine in the app.
No automation steps yet. Add an action, wait, condition, or while loop block.
Run On Device Upload the firmware-safe Action and Wait subset to the board and manage flash storage.
Device automation supports Action and Wait steps only. Upload sends the firmware-safe subset to the board.
