What is a breadboard?

A breadboard is a device designed to let you create circuits without the need for soldering. They come in various sizes, and the design can vary, but as a general rule they look something like this:

If you ve never seen one before, you might wonder how to tell which holes do what. It becomes a little easier to understand whats going on when you see the breadboard below!

Seeing it from this perspective makes it easier to understand what is going on. The two Yellow column side are typically used to connect a power source to the board. They are usually referred to as power rails. The other Blue rows running perpendicular all the way across the board are used for components in your circuit.

The power rails run horizontally as two rows at the top and bottom. Meanwhile, the vertical columns run inwards as you move down the board.

They re designed to grab onto the legs of any components pushed through the breadboard holes. This allows you to test circuits without having to worry about soldering, or making a good contact with the board. And the CONTINUITY between your circuit is achieved.

Why Use Breadboards?

An electronics breadboard is actually referring to asolderless breadboard. These are great units for making temporary circuits and prototyping, and they require absolutely no soldering.

Prototyping is the process of testing out an idea by creating a preliminary model from which other forms are developed or copied, and it is one of the most common uses for breadboards. If you arent sure how a circuit will react under a given set of parameters, its best to build a prototype and test it out.

For those new to electronics and circuits, breadboards are often the best place to start. That is the real beauty of breadboards, they can house both the simplest circuit as well as very complex circuits.
