In your exam you may be asked about developing circuits and the range of prototyping systems. This page will show you a range of techniques. When developing electronic circuits you will need to experiment with and test your design proposals.
Software packages can be very good, but they do have their limitations.
There are alternative prototyping techniques - for example, you can build a temporary circuit that allows the components to be disassembled and reused. As you can see from the diagram the holes are connected in two long rows at the top and bottom and columns of five linked holes elsewhere. Electronic components and wires can be simply plugged into the board in order to make any required circuit connections. It is recommended the top and bottom rows should be reserved to act as power rails for the circuit. Move on 2.
