Hola everyone,
I am back with a new post. Sorry guys, I had told you that I
will be posting the next post on binary conversion but I’m not. If you want post
on binary/octal/BCD/Hex conversion then post a comment or mail me on my Gmail
ID, sorry guys. So coming back to today’s post, today I am going to tell you
about a device which is very widely used in electronic circuit designing.
Just think you are going to implement a circuit which you
found or you designed. You bring all the required components like transistor,
resistors, ICs, etc. and soldered it on PCB (Printed Circuit Board); You will
get PCB of varied color and size with and without particular circuit printed on
it. So you soldered it on PCB and then when you test it you found out that it’s
not working, all the components are wasted. There are very rare chances that
you will dis-solder a component and you can use it again in other circuit. It
was all a waste of money and time. So before soldering it on PCB you can test
your circuit. Yes you can test your circuit on a device known as Bread Board.
Bread Board
The picture you see above is a Bread Board. It can be
defined as a solder-less device for temporary prototyping of electronic device.
It is solder-less which means there is no requirement of soldering to connect
the components and run the circuit. It can be used as a testing device as is
you found a defect/error in a circuit you can easily undo it. You might me
wondering how this thing connect components with each other, what is used to
make it, how we can use it? All the questions will be answered here.
What’s
inside of a Bread Board?..
If you tear off the back of a bread board you will be able
to see the construction of a bread board.
If you tear its back then it will look as shown in above
image. It is made using two material: An insulator like plastic and a conductor
i.e. metal. Plastic/Insulator is the shell of the bread board. Shell is
provided with holes in which you will insert terminals of your components.
Inside this shell there are metal strips. Metal strips are arranged such that
below every hole there is a part of the strip. When you insert terminal of the
components, it touches the metal strip and the connection is created between
them.
Alignment of the metal strip in Bread Board.
A diagram of Bread Board is shown below:
It
is very easy to say from the diagram that the above Bread Board is divided in
to Major Four Parts: A, B, C and D. To make you understand easier I will use
different color for different metal strips. So I am modifying the above diagram
so that it will be easier to explain.

Section A:
Section A is further divided in to two rows
and eight columns. In Section A the metal strip is arranged in horizontal
manner. So we can say that in Section A, holes are horizontally short or
connected with each other. But take a look at the diagram; 1st four
are red, 2nd four are purple, 3rd four are blue and 4th
four are green. This says that the four red are short or connected to each
other by a single metal strip; same goes for purple, blue and green, but the
four red and four purple are not connected with each other. In other words, the
1st four holes are short, the 2nd four are short but the
1st four and the 2nd four are not connected with each
other. Simply we can say that row-row, column-column and row-column are not
connected with each other and holes in a row/column are connected with each
other. So if you have to connect a resistor in a bread board then you have to
insert a terminal in hole of a row/column and other terminal in another
row/column.

Section B:
Section B is further divided in to one rows
and forty four column, no. of holes may differ in different Bread Board. In section
B the metal strip is arranged in vertical manner. So holes are vertically
short/connected via single metal strip. Look at the holes, the same color holes
say that they are short/connected. Row and columns are not connected to each
other. So all red in section B are connected to each other but reds and purples
are not connected to each other. Same goes on to the last column.
·
Section C:
Same as Section B
·
Section D:
Same as Section A
That’s all for today hope you like it. Next time we will see
how to make a circuit in a bread board and I will try if possible, I will be
uploading a video regarding it. If you have any query in today’s post then
