Interactive Wiring Builder

Breadboard Builder

Place modules on a visual breadboard, then click pins to draw wires between them. This first version is designed to help us experiment with lesson wiring diagrams and simple connection planning in the browser.

Drag a module by its body. Click the 180 badge or double-click a module to flip it by 180 degrees. Place components over the breadboard, then click breadboard holes to wire the occupied columns and rails together, or use Auto Wire to connect known pins automatically. When a source strip is selected, hover a compatible target to preview the wire before clicking to commit it, and use the route buttons or `[` / `]` to cycle route options first. Compatible component pins can also be clicked as proxies for their occupied breadboard strips, and matching now uses explicit per-device target rules.
