Breadboard

Introduction Breadboards are one of the most fundamental pieces when learning how to build circuits. In this tutorial, you will learn a little bit about what breadboards are, why they are called breadboards, and how to use one. Once you are done you should have a basic understanding of how breadboards work and be able to build a basic circuit on a breadboard. Bread on a breadboard So why do we call this electronic “circuit builder” a breadboard? Many years ago, when electronics were big and bulky, people would grab the nearest breadboard, a few nails or thumbtacks, and start connecting wires onto the board to give themselves a platform on which to build their circuits. Circuit on an "original" breadboard (image courtesy of Since then, electronic components have gotten a lot smaller, and we’ve come up with better ways to connect circuits, making people all over the world happy to have their breadboards back. However, we are stuck with the confusing name. Technically, these are still breadboards, but this discussion is going to be on modern, "solderless" breadboards. Why Use 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 ...

In support of Ukraine and the Ukrainian people, we have blocked access to our website to users coming from Russia and Belarus. Каждый год журнал Science Buddies охватывает десятки миллионов людей практически из всех стран мира. Мы хотим, чтобы наши ресурсы были широко доступны и использовались всеми. К сожалению, из-за неспровоцированных и насильственных действий России и Белоруссии против Украины нам больше неудобно предоставлять свои ресурсы этим странам. В поддержку Украины и украинского народа мы заблокировали доступ к нашему сайту пользователям из России и Беларуси. Science Buddies штогод ахоплівае дзясяткі мільёнаў людзей практычна з кожнай краіны Зямлі. Мы хочам, каб нашы рэсурсы былі шырока даступныя і выкарыстоўваліся ўсімі. На жаль, з-за беспрычынных і гвалтоўных дзеянняў Расіі і Беларусі супраць Украіны нам больш не камфортна прадастаўляць свае рэсурсы гэтым краінам.

If you are shopping for a solderless breadboard here on our ProtoSupplies.com site or elsewhere, you may be wondering why two basically identical looking solderless breadboards have significantly different prices. That leads to wondering what you are getting for your extra money if you pony up for the more expensive version or if you would be OK if you just get the cheaper one. Since good information on solderless breadboards can be hard to come by, we have created this guide to help. Solderless breadboards have been around for a long time and are designed to be used with compone...

Introduction The easiest way to get started building electronic circuits is by using a solderless breadboard. A breadboard is a tool for holding the components of your circuit, and connecting them together. It’s got holes that are the right size for hookup wires and the ends of most components, so you can push wires and components in and pull them out without much trouble. This lab shows how to set up a breadboard, both with an Arduino and with an independent power supply (9-12V) through a 5V Voltage Regulator (7805). By the time you finish the lab, you should have an understanding of how the holes in a solderless breadboard are connected, and how to configure your breadboard for different microcontroller projects, and even for projects without a microcontroller. You won’t always need a voltage regulator. For most microcontroller circuits, you’ll get power from your computer’s USB port, regulated through your microcontroller, to power sensors and LEDs. But for higher current projects or higher voltage projects involving components like motors or larger light sources, it’s good to know what a voltage regulator is and how to use it. If you’re using a brand new breadboard, you might want to check out What You’ll Need to Know To get the most out of this lab, you should be familiar with the following concepts beforehand.

Breadboard Breadboard later came to mean a prototype circuit built on a board with point-to-point hand wiring even though the original term referred to an expensive manufactured device. From: Embedded System Interfacing, 2019 Related terms: • Energy Engineering • Electronics • Amplifier • Binary Digit • Electric Potential • Measurer • Oscilloscope Breadboards are temporary work boards for electronic circuits. The general shape of a breadboard is shown in Fig. 6.3. Compatible with most breadboards, 24-gauge wire is used to connect circuits; solid wire, not stranded. Sometimes, kits may be available with various colors of fixed lengths to specifically fit breadboards. These are a nice convenience. Similarly, the vertical columns are connected vertically down half the width of the board. A jumper may be inserted at the middle location to connect the full width of the breadboard. The horizontal rows are typically used for power and ground, and, with the middle NOT connected, one can apply more than one power level, such as 12V, 3.3V, and ground. Fig. 6.4 shows the orientation of the board for our purposes. As noted in Fig. 6.4, vertical columns are for connections to each leg of your integrated circuit (IC). Like the three integrated circuits shown in Fig. 6.5, your IC should straddle the center valley. Breadboard (plugboard) has sets of miniature sockets laid out on a 0.1 inch grid which will accept the manual insertion of component leads and tinned copper wire (TCW) links ( ...

Breadboards are affordable and temporary devices that offer a simple approach to making electronic circuits. Just as an artist will draw a sketch before creating a work of art, breadboards are used to “sketch out” a circuit. Components are placed into the breadboard and we use the holes of the breadboard to create temporary connections between components. We can even insert microcontrollers such as the Raspberry Pi Pico into the breadboard and use them to create a circuit. So let's take a breadboard apart, learn how it works and use one to design a quick project using the Raspberry Pi Pico. (Image credit: Tom's Hardware) A common, and useful type of breadboard has connected columns along its long edges that are often marked with a red line and a black line. These are called rails and are intended to be your connections to voltage (most likely 3 to 5V when working with Raspberry Pi or Arduino) and a connection to GND. Once we connect power and ground from a power supply, all of the pins in the corresponding rail become the corresponding voltage/GND pins. This type of breadboard is often quite long, but you can purchase a half breadboard which offers the same features in a much smaller package. (Image credit: Tom's Hardware) But, on the breadboard, there is a break in a row. In the center of the board is a channel, a cut which divides the left and right sides of the board. The break gives us more space to prototype projects but should we need to bridge the channel we can use...

A thin plastic board used to hold electronic components (transistors, resistors, chips, etc.) that are wired together. Used to develop prototypes of electronic circuits, breadboards can be reused for future jobs. They can be used to create one-of-a-kind systems but rarely become commercial products. See The breadboard contains spring clip contacts typically arranged in matrices with certain blocks of clips already wired together. The components and jump wires (assorted wire lengths with pins at both ends) are plugged into the clips to create the circuit patterns. The boards also typically include metal strips along the side that are used for common power rails and signal buses. Breadboard In this breadboard, both components and jump wires plug into the top.

A Motherboard Breadboard In this prototype of the first IBM PC motherboard, the components are plugged into the breadboard (top) and wired together underneath (bottom). After the circuits were thoroughly tested, the wires were turned into printed circuits on the final product. See (Images courtesy of IBM.)
