What is an Arduino breadboard and its types

Breadboard Explanation

What is an Arduino breadboard? - When we make an Arduino electronic prototype, there will be many obstacles that we will appear, One example is the relationship between components. To make it easier for us to carry out the prototyping process in connecting one component and another, we use a breadboard.


Definition of Bread Board

Breadboard is a thin plastic board that has holes, in which there are conductor strips that have a certain direction and trajectory (see picture below). Breadboard has other names such as Project Board or Proto Board (Prototype Board).

Usually this Prototype board is only used in electronic testing, where each component leg is inserted into the conductor holes to be able to connect to other components.

The use of this board is highly recommended if the circuit is still in the development stage, because with this we can easily and quickly do research and development.

Breadboard Function

The main function of this board is to connect one component to another without soldering. When we're testing circuits and doing research, we're basically changing paths and components a lot. Therefore, the components that we use are not easily damaged, unlike making a prototype by doing soldering. More components will have to be replaced.

Because of this convenience, many students, students or teachers use breadboards in making electronic circuits.

Strip Conductor Direction

Inside the bread board there are conductors with a certain pattern. So that each hole is not connected to each other. As an example we take a project board consider the following picture:

Usually each breadboard is divided into 3 parts,  the top, middle and bottom. At the top and bottom, the direction of the connection path is horizontal. While in the middle, the direction of the connection is vertical.

In the middle there is an empty, it's pointless for laying IC, the size is suitable for laying IC or mikrokotroller purposes.

Types of Breadboard

In general, there are 3 types of breadboards based on their size, namely Mini, Medium, and Large Breadboards. The size of this project board will affect the number of connection points.

  • Mini Breadboard
    This type has 170 connection points. This type is very widely used for Arduino breadboard projects as a sensor holder or input for Arduino, because of its relatively small size.

  • Medium Breadboard
    This type has 400 connection points. In addition, for this type there is a presser part on the side which is useful for gluing or combining breadboards to other breadboards for the use of a relatively large number of prototype circuits..

  • Large Breadboard
    This type has a total of 830 connection points. Just like Medium Breadboard, it has an adhesive side on the side of the body. The point is to combine various breadboards for wider purposes.

Examples of using Breadboard

For example, the use of the Large type breadboard is as shown in the following image. Insert each leg of the component into the hole, then it will always connect with other points. This image is taken from wikipedia.

Tips for Using Breadboarding

It's important to convey some tips that can make it easier for you to use this breadboard. Here are the tips:

  • For medium and large types, use the top side (there are two rows of holes) and the bottom (there are two rows of holes) for the power and ground lines only.
  • Use the red wire for power (VCC) and black for ground (GND).
  • If you use jumper cables to connect one hole to another, use a flat cable, which makes it easier for us to design and also beautify our circuit.
  • If you are using an IC, do not cross the jumper cable over the IC because it will make the IC difficult to remove and operate.
