There are many ways to build a circuit , depending on which tools are available and whether time is sufficient. When designing new circuit of FIG usually finalized before the circuit configuration and welding, the first circuit built on a breadboard and test its functionality. This allows problems to be discovered early in the initial phase and sufficient time to modify the design without being forced to modify the welded parts.

Usually the first version of the design is implemented on a carrier that can be kept relatively long, such as a printed circuit board or a universal board.

N ways to build a circuit : wrap / solder pin

By nailing a number of nails to the board, a simple circuit is made, and then the wiring/soldering can be routed between the nails. I designed my first circuit like this when I was studying GCSCs at school. If the system is relatively complex, you need to use a special board and routing tools.

This method works well for both basic circuit design and teaching. When analyzing the principle, we can even replace the component object on the board with the circuit drawing. But if the circuit is extremely complex, especially if your design is already based on an integrated circuit board, then the breadboard is more suitable.

N ways to build a circuit : a breadboard that does not need to be welded

Simple breadboards (also known as inserts or plug-in boards) are more suitable for temporary circuit testing than soldered boards. The breadboard consists of a plastic plate and an array of holes, each of which is connected to each other so that the components inserted into the same array module are connected to each other.

The breadboard is easy to use and does not damage the components, while the integrated circuit is easy to plug and connect to other components. Other types of carriers are often used in conjunction with potentiometer mounts and the like. A solid wire is required to connect to the breadboard (if you are used to a relatively flexible multi-core wire, you need to prepare a solid wire for the breadboard). If you design multiple circuits, it is best to buy a package of wire that has been cut to length. Although more expensive than standard length welding wire, it eliminates the cutting process.

The 25-minute e-training tutorial uses a buzzer circuit as an example to explain how to build a circuit on a breadboard.
