How to use the bench (mouse, touch, or keyboard)
- Add parts: drag a part from the tray onto two posts of the board (it snaps), or use Add a part in the side panel.
- Wire: drag from one post to another. Tap a wire or a part to select it; drag a part to move it, or drag it back to the tray to remove it (or press Delete).
- Switches and meters: tap a switch to flip it. Turn the multimeter's dial and drag its red and black probe tips onto posts.
- Keyboard: every part is in the Parts list in the side panel; wires can be added by post name (for example B1 to B3).
- Time: Space play / pause · → step · R reset · Z / X zoom · H help. Play matters for the moving charges, bulbs warming up and capacitors charging; the readings are always live.
