How to use a Breadboard

in Arduino Getting Started

Breadboards are one of the most fundamental pieces when learning to build circuits. For those who are new to electronics and circuits, breadboards are the best way to start. Since breadboards are available in all sizes, you can use them for simple and very complex circuits. In this tutorial, you will learn more about what breadboards are and how to use one. Once you read this tutorial, you should have a basic understanding of how breadboards work, and you will be able to build a basic circuit on a breadboard. Firstly, a breadboard is a synonym for a solderless breadboard. Therefore, breadboards are great for experimenting with circuits, building prototypes because they do not require soldering.

A breadboard is a tool for holding the components of your circuit and connecting them. This section will cover how to set up a breadboard that allows you to use the power provided by the Arduino board. You could also power the breadboard directly from the power supply. Before you do this, please visit the tutorial on power supplies. The easiest way to get started building electronic circuits is by using a solderless breadboard.

Breadboards are great since they are easy to use for testing ideas, components, or just for fun. You can rewire things always without the need to solder parts together. This property of the breadboard makes it ideal for prototyping. Using breadboards enables you to avoid connecting LEDs, resistors, or other electronic components directly to the Arduino Board.

Breadboards are in various sizes and designs. You can get an excellent solderless board for under 10 euros.

Rows and column on a breadboard.

You may have noticed that breadboards have numbers and letters on them to mark various rows and columns. These rows and numbers are there to help you during the build of the circuit. Circuits can get complicated, and all it takes is one misplaced wire to make the entire circuit not working. Therefore, rows and numbers are there to help you.

Power Rails

There are two long rows of holes with black or red lines on each side of the board. All the holes in each of the lines are connected.

Keep in mind that the markings on the breadboard are just guidelines. You can also reverse the stripes if you would like to. However, this is not recommended since all tutorials will build on the above assumptions.

The two long rows with black or red lines are called power rails that run vertically along the sides.

When you are building circuits, you need to supply power to a lot of parts. Power Rails give you access to power more easily wherever you need it in your circuit. Usually, the negative stripe is labeled with “” or a black stripe, while the positive stripe is labeled with “+” or a blue stripe.

The power rails on either side are not connected. So if you would like to have both power rails with the same power source, you need to connect the rails through wires.

Just remember that the circuit you’re building doesn’t have to be in the same location on the breadboard as described in the following tutorials. It doesn’t even have to look similar. As long as all the electrical components are connected, you can build your circuit any way you’d like!

Basic Breadboard layout

We will use different microcontroller boards on this website, but there is a standard layout of the breadboard for each one.

The figure shows an Arduino Uno connected to a solderless breadboard. The Arduino Uno’s 5V output connects to the red columns on the breadboard’s left side. The blue column connects connected to the ground of the Arduino Uno Board. The red and blue rows of both sides are connected.

One thing to consider is that in both examples above, the power rails will enable 5-volt and 3-volt to the power rails. If you want more voltage to the rails or more ampere, the board can deliver you will need another power source.
