What are the basic constituents of an electrical circuit? Of course a power source, conducting paths, and a load. Theoretically the connections and functioning of a particular circuit may look pretty straightforward. However building an electrical circuit physically and making it work can be totally a different ball game.
Suppose, you have a schematic and are interested in testing it practically or want to construct your own designed electronic prototype, let’s say you want to illuminate a few LEDs using a power source from a power supply unit. Definitely, procuring the required parts won’t be difficult, and also a continuously variable DC power supply unit should be readily available to you.
The most difficult part lies in integrating the components together into the required circuit configuration. Nope, you can’t do it by twisting their leads together - that can be tiresome and clumsy. Using a soldering iron may be handy for the experts, but a neophyte can make a total mess with it.
Moreover for a beginner, trials using such rather complicated methods will mostly produce failures and will also eliminate the chances of reusing the components involved.
The makers of breadboards must have realized this problem a long time ago, and that’s why we now have this intelligent piece of circuit construction device at our disposal- exactly for the purpose.
One may simply use a breadboard for inter-connecting different electrical and electronic components together by plugging them into its sockets and easily build and observe a prototype circuit working without the need of using tentative and cumbersome means like a soldering iron.
Wondering how to use a breadboard? As complete a breadboarding tutorial as I can come up with is discussed here, so let’s move on.
