A breadboard is a rectangular plastic board with a bunch of tiny holes in it. These holes let you easily insert electronic components to prototype (meaning to build and test an early version of) an electronic circuit, like this one with a battery, switch, resistor, and an LED (light-emitting diode). To learn more about individual electronic components,etc.,
The connections are not permanent, so it is easy to remove a component if you make a mistake, or just start over and do a new project.
This makes breadboards great for beginners who are new to electronics.
Prototyping is the process of testing out an idea by creating a preliminary model from which other forms developed or copied, and it is one of the most common uses for breadboards. If you aren’t sure how a circuit will react under a given set of parameters, it’s best to build a prototype and test it out.
A breadboard is a construction base for prototyping of electronics. The solderless breadboard does not require soldering, it is reusable. This makes it easy to use for creating temporary prototypes and experimenting with circuit design. For this reason, solderless breadboards are also popular with students and in technological education. Older breadboard types did not have this property.
A stripboard and similar prototyping printed circuit boards, which used to build semi-permanent soldered prototypes or one-offs, cannot easily be reused. A variety of electronic systems prototyped by using breadboards, from small analog and digital circuits to complete central processing units (CPUs).
The top of the metal rows has little clips that hide under the plastic holes. These clips allow you to stick a wire or the leg of a component into the exposed holes on a breadboard, which then hold it in place. Once inserted that component will be electrically connected to anything else placed in that row. This is because the metal rows are conductive and allow current to flow from any point in that strip.there are only five clips on this strip. Thus, we can only have up to five components connected in one particular section of the breadboard. There are 4 power rails in ends of the breadboard.
