The chips

Skills: Build

Statement

The red lead stops short of the resistor: the loop is open. On this board, holes are not connected to each other.

Take the Jumper chip from the palette (or key C), then drag from the end of the lead to the left leg of the resistor (from A2 to E2): a line of chips joins the holes. Each chip bridges two neighbouring holes, with no resistance.

2 hints from Bastaya available in the lab
Solution

Four chips join A2, B2, C2, D2 and E2: those five holes are now a single circuit node.

How does it work?

Each big hole is a circuit node: you push one leg of a component into it. The 4 small holes around it are connected to it: chips and leads plug in there.

  1. Place a component Drag it from the palette: it snaps onto the grid. R rotates it.
  2. Bridge neighbouring holes Pick the jumper chip (or C) and drag on the board: bridged holes become a single node.
  3. Draw a lead For long links and the power supply: from one big hole to another, or to a terminal.
  4. Close the loop The circuit is solved live (Ohm, Kirchhoff) and the diagram follows.
