Bread Board

Bread board

A bread board is a solder-less device for temporary prototype with electronics and test circuit designs. Most electronic components in electronic circuits can be interconnected by inserting their leads or terminals into the holes and then making connections through wires where appropriate. Bread boards are one of the most fundamental pieces when learning how to build circuits. In this tutorial, you will learn a little bit about what bread boards are, why they are called bread boards, and how to use one. Once you are done you should have a basic understanding of how bread boards work and be able to build a basic circuit on a bread board.

Why Use Breadboards?

An electronics bread board (as opposed to the type on which sandwiches are made) is actually referring to a solderless bread board. 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 bread board. 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.

For those new to electronics and circuits, bread boards are often the best place to start. That is the real beauty of bread boards–they can house both the simplest circuit as well as very complex circuits. As you’ll see later in this tutorial, if your circuit outgrows its current bread board, others can be be attached to accommodate circuits of all sizes and complexities.

Another common use of bread boards is testing out new parts, such as Integrated circuits (ICs). When you are trying to figure out how a part works and constantly rewiring things, you don’t want to have to solder your connections each time.

As mentioned, you don’t always want the circuit you build to be permanent. When trying to duplicate a customer’s problem, SparkFun’s Technical Support team will often use bread boards to build, test, and analyze the circuit. They can connect the parts the customer has, and once they’ve gotten the circuit setup and figured out the problem, they can take everything apart and put it aside for the next time they need to do some troubleshooting.
