Physical breadboard view
Shows where each leg and jumper wire goes on a real breadboard. It is built from your schematic, and you can rearrange it — move and rotate parts, recolour and re-route wires. The wiring always stays electrically correct.

Assembly steps
Breadboard basics: the 5 holes in each numbered column (a–e, or f–j) are joined inside. The long red/blue rails are joined along their length.
