How to Use a Breadboard Step 1: Types of Breadboard. There are various types of usloveescort.comoard can be found in various sizes and Step 2: How It Works. Basically, a bread board is an array of conductive metal clips encased in a box made of . The best way to explain how a breadboard works is to take it apart and see what’s inside. Using a smaller breadboard it’s easier to see just how they function. Terminal Strips. Here we have a breadboard where the adhesive backing has been removed. You can see lots of horizontal rows of metal strips on the bottom of the breadboard.
Many electronics projects use something called a breadboard. What is a breadboard, and how do you use it? This tutorial video will give you a basic introduction to breadboards and explain how to use them in beginner electronics projects; you can also read more details and see more examples in the text sections. 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, see our Electronics Primer. 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. You can use breadboards to make all sorts of fun electronics projects, from different types of robots or an electronic drum set, to an electronic rain detector to help conserve water in a garden, just to name a few.
You might be wondering what any of this has to do with bread. The term breadboard comes from the early days of electronics, when people would literally drive nails or screws into wooden boards on which they cut bread in order to connect their circuits. Luckily, since you probably do not want to ruin all your cutting boards for the sake of an electronics project, today there are better options.
Modern breadboards are made from plastic, and come in all shapes, sizes, and even different colors. While larger what was it like to go to the globe theatre smaller sizes are available, the most common sizes you will probably see are "full-size," "half-size," and "mini" breadboards. Most breadboards also come with tabs and notches on the sides that allow you to snap multiple boards together.
However, a single half-sized breadboard is sufficient for many beginner-level projects. Technically, these breadboards are called solderless breadboards because they do not require soldering to make connections. Soldering pronounced SAW-der-ing is a method where electronic components are joined together by melting a special type of metal called solder. Electronic components can be soldered directly together, but more commonly they are soldered onto printed circuit boards PCBs.
PCBs are what you will see if you take the cover off many electronic devices, like a computer or cell phone. Frequently, engineers will use solderless breadboards to prototype and test a circuit before building the final, permanent design on a PCB.
This image shows the same circuit battery, switch, resistor, and LED built three different ways: on a solderless breadboard leftwith the components soldered directly together middleand on a printed circuit board right :.
Soldering is a great technique to learn if you are interested in electronics, but the connections are much more permanent and it requires purchasing some tools to get started.
The rest of this tutorial will focus on solderless breadboards, but you can read our soldering tutorial to learn more about soldering. So, how do electronic components fit into a breadboard? Many electronic components have long metal legs called leads pronounced "leeds". Sometimes, shorter metal legs are referred to as pins instead. Almost all components with leads will work with a breadboard to learn more about these components and which types work with a breadboard, see the Advanced section.
Breadboards are designed so you can push these leads into the holes. They will be held in place snugly enough that they will not fall out even if you turn the breadboard upside-downbut lightly enough that you can easily pull on them to remove them. You do not need any special tools to use a solderless breadboard.
However, many electronic components are very tiny, and you may find them difficult to handle. A pair of miniature needle nose pliers or tweezers may make it easier to pick up small components. The leads can fit into the breadboard because the inside of a breadboard is made up of rows of tiny metal clips. This is what the clips look like when they are how to make instant rice flour dosa from a breadboard.
Most breadboards have a backing layer that prevents the metal clips from falling out. The backing is typically a layer of sticky, double-sided tape covered by a protective layer of paper. If you want to permanently "stick" the breadboard to something for example, a robotyou just need to peel off the paper layer to expose the sticky tape underneath. In this picture, the breadboard on the right has had its backing removed completely so you can see all the metal clips.
The breadboard on the left still has its sticky backing, with one corner of the paper layer peeled up. Most breadboards have some numbers, letters, and plus and minus signs written on them. What does all that mean? While their exact appearance might vary from breadboard to breadboard, the general purpose is always how to use a breadboard same. These labels help you locate certain holes on the breadboard so you can follow directions when building a circuit.
Row numbers and column letters help you identify individual holes in the breadboard, just like cells in a spreadsheet. For example, all of the highlighted holes are in "column C. They are called the busesalso referred to as railsand are typically used to how to restore win 7 electrical power to your circuit when you connect them to a battery pack or other external power supply.
Similarly, negative bus and ground bus both refer to one next to the blue or black line with the minus - sign. Sound confusing? Use this table to help you remember—there are different ways to refer to the buses, but they all mean the same thing.
Do not worry if you see them referred to by different names in different places for example, in different Science Buddies projects or other places on the internet. Sometimes you might hear "power buses" or rails used to refer to both of the buses or rails together, not just the positive one.
Note that there is no physical difference between the positive and negative buses, and using them is not a requirement. The labels just make it easier to organize your circuit, similar to color-coding your wires.
Remember that the inside of the breadboard is made up of sets of five metal clips. This means that each set of five holes forming a half-row columns A—E or columns F—J is electrically connected. It is not connected to hole A2, because that hole is in a different row, with a separate set of metal clips. It is also not connected to holes F1, G1, H1, I1, or J1, because they are on the other "half" of the breadboard—the clips are not connected across the gap in the middle to learn about the gap in the middle of the breadboard, see the Advanced section.
Unlike all the main breadboard rows, which are connected in sets of five holes, the buses typically run the entire length of the breadboard but there are some exceptions. This image shows which holes are electrically connected in a typical half-sized breadboard, highlighted in yellow lines. Buses on opposite sides of the breadboard are not connected to each other. Typically, to make power and ground available on both sides of the breadboard, you would connect the buses with jumper wires, like this.
Make sure to connect positive to positive and negative to negative see the section on buses if you need a reminder about which color is which. Note that exact configurations might vary from breadboard to breadboard.
For example, some breadboards have the labels printed in "landscape" orientation instead of "portrait" orientation. Some breadboards have the buses broken in half along the length of the breadboard useful if you need to supply your circuit with two different voltage levels.
Most "mini" breadboards do not have buses or labels printed on them at all. There may be small differences in how the buses are labeled from breadboard to breadboard. Some breadboards have the positive buses on the left and the negative buses on the right, and on other breadboards, this is reversed.
A breadboard diagram is a computer-generated drawing of a circuit on a breadboard. Unlike a circuit diagram how much does container store pay a schematic which use symbols to represent electronic components; see the Advanced section to learn morebreadboard diagrams make it easy for beginners to follow instructions to build a circuit because they are designed to look like the "real thing.
Sometimes, breadboard diagrams might be accompanied by or replaced with written directions that tell you where to put each component on the breadboard. For example, the directions for this circuit might say:. The short answer is "no. To understand this, it helps to understand how a breadboard's holes are electrically connected.
There are different ways to change the physical layout of a circuit on a breadboard without actually changing the electrical connections. For example, these two circuits are electrically identical; even though the leads of the LED have moved, there is still a complete path called a closed circuit for electricity to flow through the LED highlighted with yellow arrows. So, even if the directions say "put the LED's long lead in hole F10," the circuit will still work if you put it in hole F12 instead but not if you put it in hole F9 or F11, because different rows are not connected.
However, you can also completely rearrange the components on the breadboard. As long as the circuit is electrically equivalent, it will still work. Even though this circuit "looks different" than the previous two because the components have been rearranged, electricity still follows an equivalent path through the LED and the resistor.
Jumper wires are wires that are used to make connections on a breadboard. They have stiff ends that how to stop toddler from scratching mosquito bites easy to push into the breadboard holes.
There are several different options available when purchasing jumper wires. Flexible jumper wires are made of a flexible wire with a rigid pin attached to both ends. These wires usually come in packs of varying colors.
This makes it easy to color-code your circuit see the section on color-coding. While these wires are easy to use for beginner circuits, they can get very messy for more complicated circuits; because they are so long, you will wind up with a tangled nest of wires that are hard to trace sometimes called a "rat's nest" or "spaghetti".
Jumper wire kits are packs of pre-cut lengths of wire that have their ends bent down 90 degrees, so they are ready to put into a breadboard. The kits are available in larger and how to learn piano book sizes.
These kits are very convenient because they come with wires of many different pre-cut lengths. The disadvantage is that there is typically only one length of each color. This can make it difficult to color-code your circuit for example, you might want a long black wire, but your kit might only have short black wires.
Your circuit will still work just fine, but color-coding can help you stay more organized again, see the section on color-coding for more information. Notice how this circuit looks much less messy than the previous one, since the wires are shorter.
Finally, you can also buy spools of solid-core hookup wire and a pair of wire strippers and cut your own jumper wires. This is the best long-term option if you plan on doing lots of electronics projects, because you can cut wires to the exact length you need, and pick which colors you want.
It is also much more cost-effective per length of wire. Buying a kit of six different colors is a good place to start.

Although this method is still used today, there is something that makes prototyping much easier, breadboards! A wire-wrap circuit image courtesy of Wikipedia user Wikinaut.
When you picture a breadboard in your head, you may envision a big piece of wood and a large loaf of freshly baked bread. Circuit on an "original" breadboard image courtesy of mischka and their awesome literal breadboard tutorial. However, we are stuck with the confusing name.
Technically, these are still breadboards, but this discussion is going to be on modern, "solderless" breadboards. An electronics breadboard as opposed to the type on which sandwiches are made is actually referring to a solderless 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.
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.
As you'll see later in this tutorial, if your circuit outgrows its current breadboard, others can be be attached to accommodate circuits of all sizes and complexities.
Another common use of breadboards is testing out new parts, such as Integrated circuits ICs. Here we have a breadboard where the adhesive backing has been removed. You can see lots of horizontal rows of metal strips on the bottom of the breadboard.
A SparkFun Mini Breadboard from the top left and the same breadboard flipped over with the adhesive back removed right. The tops of the metal rows have little clips that hide under the plastic holes. Each metal strip and socket is spaced with a standard pitch of 0. 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. A single strip of conductive metal removed from the above breadboard.
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. Notice that there are only five clips on this strip. This is typical on almost all breadboards. Thus, you can only have up to five components connected in one particular section of the breadboard. The row has ten holes, so why can you only connect five components?
This ravine isolates both sides of a given row from one another, and they are not electrically connected. An LED inserted into a breadboard. Notice how each leg of the LED is placed on either side of the ravine. This prevents the connections to the LED from being shorted. Aside from horizontal rows, breadboards usually have what are called power rails that run vertically along the sides.
A medium-size breadboard with the adhesive back removed to expose the power rails. When building a circuit, you tend to need power in lots of different places. The power rails give you lots of easy access to power wherever you need it in your circuit. It is important to be aware that the power rails on either side are not connected, so if you want the same power source on both sides, you will need to connect the two sides with some jumper wires.
Keep in mind that the markings are there just as a reference. Two jumper wires used to connect the power rails on both sides. Earlier we mentioned the ravine that isolates the two sides of a breadboard. This ravine serves a very important purpose. Many integrated circuits , often referred to as ICs or, simply, chips, are manufactured specifically to fit onto breadboards.
In order to minimize the amount of space they take up on the breadboard, they come in what is known as a Dual in-line Package , or DIP. These DIP chips salsa anyone? That is where the separation in the middle of the board comes in handy. Thus, we can connect components to each side of the IC without interfering with the functionality of the leg on the opposite side.
You may have noticed that many breadboards have numbers and letters marked on various rows and columns. These don't serve any purpose other than to help guide you when building your circuit. Circuits can get complicated quickly, and all it takes is one misplaced leg of a component to make the entire circuit malfunction or not work at all. If you know the row number of the connection you are trying to make, it makes it much simpler to plug a wire into that number rather than eyeballing it.
Many books and guides have circuit diagrams for you to follow along while building your circuit. Some breadboards come on a platform that has binding posts attached to it. These posts allow you to connect all kinds of different power sources to your breadboard. We'll cover these more in the next section. When building your circuit, you are not confined to stay on just one breadboard. Some circuits will require a lot more space. Many breadboards have little nubbins and slots on the sides, and some even have them on the tops and bottoms.
These allow you to connect multiple breadboards together to form the ultimate prototyping surface. Four SparkFun mini breadboards connected together. Some breadboards also have an adhesive backing that allow you to stick them to many different surfaces. These can come in handy if you want to attach your breadboard to the inside on an enclosure or other project case. The Arduino has multiple power and ground pins that you can connect to the power rails or other rows on a breadboard.
Now any leg or wire connected to that row will also be connected to Ground. The Arduino usually gets its power from the USB port on a computer or an external power supply such as a battery pack or a wall wart.
As mentioned in the previous section, some breadboards have binding posts that allow you to connect external power sources. The first step to using the binding posts is to connect them to the breadboard using some jumper wires. Although it would seem that the posts are connected to the breadboard, they are not.
With that, we have to connect wires to the posts in order to connect them to the breadboard. To do that, unscrew the post until the hole going through it is exposed.
Slide the stripped end of your jumper wire through the hole, and screw the post back down until the wire is firmly connected. Typically, you only need to connect a power and ground wire from the posts to the breadboard. If you need an alternate power source, you can use the third post. Now your posts are connected to the the breadboard, but there is still no power.
You can use many different methods to connect power to the posts, and, thus, to the breadboard.
