What is Breadboard?
A breadboard is a circuit board that is used to make temporary circuits. It is a device having electronics and test circuit designs. The electronic elements inside the electronic circuits can be interchanged by inserting the terminals and leads into holes and later connecting it with the help of appropriate wires. The device has stripes of metal below the board that connects the holes placed on the top of the board. The connections of the breadboard are mostly temporary and the elements can further be reassembled and reused without any damage. Breadboards are generally used in electrical engineering. Engineers make use of breadboards in order to test different products made by them. Using breadboard is the most efficient way of testing and also they are cost effective. They can be reused again and again for the purpose of testing. Today, starting from tiny analog, digital circuits to big complicated CPU’s everything can be tested with the help of this.
Breadboards earlier were made of copper wires or terminal strips. These days it is made up of white plastic and is a breadboard that can be plugged. Breadboards are solderless and they are made of two kinds of strips i.e. terminal and bus strips. Terminal strips help in holding the electronic elements while the bus strip is used to power electric power to all the electronic components. You can find manufacturers selling solderless breadboards very easily, some manufactures sell the bust and terminal strips separately and some sell it together.
A breadboard is a circuit which if of a temporary nature used for the purpose of testing and prototyping circuits. It is easy to prototype circuits with the help of breadboards because it is fast and easy. Breadboards are generally used to test circuits. As this device have holes in it. In order to form a circuit, wires are inserted simply inside the holes. An advantage of using a breadboard is that the positions of the wires can be changed if they are placed in a wrong order. In the below diagram you can see alphabets are used in order to identify vertical columns and numbers are used in order to identify vertical columns.
In the below diagram you can see how a resistor of 380 ohm and a LED are set up on the breadboard. A 9 volt battery is eventually attached to the LED light. Replace the current resistor with a resistor having 680 ohm you can see the resistance to be greater and the LED light to be dimmer.
A breadboard as mentioned before is used to make temporary circuit for testing and other purposes. The advantage of using a breadboard for testing is that connection can be changed if they are wrong. Also the parts of the circuit do not get damaged and can easily be reused. A breadboard generally consists of lots of holes so that wires can easily be pushed in. testing for almost every electronic projects starts from the breadboard. The breadboard has many tiny sockets likes holes arranged in a 0.1 grid. The leads that most elements have can easily be pushed inside these holes. The ICs are pushed inside across to the gap with their dot on the left. Standard wires cannot be used for breadboard as they get damaged easily and hence they require single core plastic coated wires that have 0.6mm diameter. Standard wires if used can also lead to damage of the board.
The above diagram shows how the holes of a breadboard are connected. The bottom and the top rows are connected horizontally across as the red and the black line denotes. The power supply is connected to both the black and red rows. The other rows are connected in a vertical manner which consists of five rows each without any links to the across the centre. In this way there are separate blocks of connections to each of the ICs pin. Now this was the connection in a small breadboard.
In case of large breadboards, there are breaks half way in the top and the bottom rows of the power supply. It is always better to link across the gap before you start building circuit. If you do not link it then that part of the circuit will not have any power supply.
The virtual breadboard is generally used to test and design embedded software that is in a high level interactive circuit. It is used for prototyping the hardware from these designs. People find the virtual breadboard easier to utilize than the normal ones because it has a high approach. Also it is faster in tis working and helps in testing new ideas and circuit variations.
Virtual breadboards are usually used in place of real breadboards because they are fast in working. Also it is fast in performing experiments and testing electronic embedded applications. Many experimenters prefer using virtual boards for experiments than real boards as its functioning is easy. The virtual board is popular in many universities around the world since the 1999.
A virtual breadboard is also called as VBB and makes use of microcontrollers featuring Makeable bereadbaord designs. A virtual breadboard helps in making your projects easier and helps you do your experiments I a simple way. There are different versions of VBB that are available which users can use according to their need. It is always better to use a virtual breadboard than a real one as the virtual ones are more reliable. So if you are in a hurry and want immediate results it is advised that you make use of VBB.
On the whole, using a breadboard is very easy and as it gives immediate results everyone prefers using it for testing different gadgets and electronic products.
