every hole in a strip is the same node — the rest is Ohm's law

Electronics Lab 01 · Circuit Sandbox — pick a part, then click two holes · click a switch to flip it

Parts tray

Pick a part, then click its holes — on this mini-board or on the 3D breadboard. The potentiometer has THREE pins: END → WIPER → END.

Voltage mode — dial set to V

Pick V, A or Ω to arm the probes — or click the dial on the 3D meter to turn it. Touch the two probes ACROSS a part (in parallel) to read the potential difference between them.

Breadboard
