There are multiple approaches to building a circuit, depending on the tools you have and the time available. When designing a new circuit, especially for projects like FIG, the initial design is usually finalized before moving to the actual configuration and soldering. The first version of the circuit is often built on a breadboard to test its functionality. This allows early detection of issues and gives enough time to refine the design without having to modify already soldered components.

The first prototype is typically implemented on a more permanent carrier, such as a printed circuit board (PCB) or a universal board. These provide stability and make it easier to keep the circuit for future use or modifications.

Several ways to build a circuit: Wrap/Solder Pin

One method involves using nails on a board to create a simple circuit. Wires or solder can then be routed between the nails. I used this technique when I was studying GCSCs at school. For more complex systems, a specialized board and routing tools may be necessary.

This approach is great for basic circuit design and educational purposes. When analyzing the circuit, you can even replace the physical components with their schematic representations. However, if the circuit is very complex or based on an integrated circuit, a breadboard might be more suitable.

Another way to build a circuit: Breadboard (No Soldering Required)

Breadboards, also known as plug-in boards, are ideal for temporary circuit testing. They consist of a plastic base with a grid of holes that are internally connected. Components inserted into the same row are electrically connected, making them easy to use and reconfigure.

Breadboards are user-friendly and don’t damage components. They’re especially useful for working with integrated circuits, which can be easily plugged in and connected to other parts. Many breadboards come with additional mounts for potentiometers and other components. A solid wire is typically needed for connections, although flexible multi-core wires can also be used if prepared properly. If you're building multiple circuits, it's efficient to purchase pre-cut wires in standard lengths, even if they cost a bit more—this saves time by eliminating the need to cut wires yourself.
