Components have wires or contacts that can be electrically joined together by soldering. The components are usually soldered to copper tracks on a circuit board known as a pcb. This makes neat, safe connections (or joints), The model circuit board below, is a grid made up from 0.5cm squares. The orange lines that have appeared show you where to place the copper tracks. |

Step 2
To make this circuit you will first need to put some copper tracks onto a circuit board so the components can be soldered together. The orange lines on the grid show you where they go.
Workout the length of each line and enter the values below. The copper tracks can then be dragged into position.
STEP 2 Creating a To connect them, we now need to place copper tracks on the orange lines. This will create a circuit board for us to solder to. |
