Large breadboards are big in size, very useful for major projects which are located onto a metal plate. These boards are available with four colored posts which can be used through a bench-top supply. These boards include bumpers to maintain the board from slipping in the region of your desk. How to Choose a Breadboard? In the initial days of electronics manufacturing, engineers and designers have realized that sometimes designing a temporary circuit needs without soldering the components. So, an engineer took cardboard and arranged several rows into it to place nails. As per the circuit diagram, they placed components and nailed them through short wire pieces. The electrical connection can be provided by wrapping wire or soldering around the nails, and then components could be soldered to the wires. But by using cardboard, some resistive features may cause power loss. So, to overcome this process, at present breadboards were implemented by the scientists. Breadboards are one of the most essential rectangular pieces, used to build different circuits without soldering. This article discusses an overview of what is a breadboard, working, types and applications. What is a Breadboard?

Usually, you have to attach a power as well as the ground wire from the posts toward the breadboard. If you require any additional power source, then you can utilize the alternate post. Once the posts are connected to the breadboard, then you can use several methods to fix the power supply toward the posts as well as toward the breadboard. Benchtop Power Supplies Benchtop power supplies mainly used in electronics labs which provide an extensive range of current & voltage to your circuit. A banana connector is used to give a power supply toward the binding posts. The power supply to a breadboard can be supplied with binding posts using banana cables. The wires you use are best if they are of a solid core and a certain size. The reasons for this are explained in my article Wires for breadboards, and contains more detail on this subject. We are using a 9v battery, and a typical LED is rated for ~15mA. If we plug those values into the formula and solve for the resistance, we can determine the minimum value needed for our resistors.It is important to be especially careful when inserting integrated circuits into the breadboard holes. Unless the IC pins are straight, it is very easy to crush the pin into a zigzag shape or fold the pins underneath the body of the IC. Either way the result is a bad connection or no connection at all. Different electronic components are compatible with breadboards like resistors, capacitors, switches, diodes, etc. These components which include lengthy metal legs are known as leads whereas components that include shorter metal legs are known as pins. All the electronic components including different sizes of leads will function through a breadboard. In case you're curious about why we need resistors, they prevent the diodes from drawing an unrestricted amount of current from the battery. These resistors act as current limiters, which puts a cap on how much current a LED may draw. The specific value of these resistors varies based on the voltage and the LED's current rating, and we can determine this through Ohm's Law
Always use the top and bottom bus rails for power supply connections. Power the integrated circuits and other devices from these bus rails and not directly from the power supply. Breadboards can be used semi-permanently or permanently for home projects, but printed circuit boards are going to be more stable and durable over time compared to their protoboard counterpart, the breadboard. Types of Breadboards Powered Breadboards vs. Standard Breadboards The alternatives of breadboards which need soldering are veroboards & protoboards. The most similar type of board is the Veroboard which includes holes that are connected through a single axis. Another alternative is protoboards which include similar kinds of holes but none of the holes on the board are connected. Advantages If the terminal of the component does not place into the hole of a breadboard, then a connecting wire can be soldered to the lead of a component that will insert in the breadboard hole. AdvantagesSome manufacturers provide high-end versions of solderless breadboards. These are typically high-quality breadboard modules mounted on a flat casing. The casing contains additional equipment for breadboarding, such as a power supply, one or more signal generators, serial interfaces, LED display or LCD modules, and logic probes. [21]
