Elec Principles

Hello dear friends we want to learn something new every time and in that process we always do mistakes first. As it is well known we learn from our mistake. And we have something in our electronics magic-box which is going to save us from messy electronics PCB plates and doing soldering all the time.

So, my this article is about our learning board used in electronics project mainly known as "Breadboard". Isn't it funny bread-board but don't worry we don't need to eat it we have to do something interesting with it. Many times i asked why it is known as breadboard, really i don't know the answer but i used to say that since also have the pores as we have in breads :) .

So with learning objective let us start with the "Bread-boards" :)

 

INTRODUCTION

A breadboard also is  known as protoboard . It is  a type of solder-less electronic circuit building. You can build a electronic circuit on a breadboard without any soldering ! Best of all it is reusable. It was designed by Ronald J Portugal of EI Instruments Inc. in 1971. 

HOW IT WORKS 

As i already told you there are a lot of holes in the board to place components and power supply. Actually these holes are arranged in a particular fashion and these are shorted with metal clips present inside the board in this manner. 

There are basically to type of strips in a bread board BUS OR HORIZONTAL STRIPS and SOCKET OR VERTICAL STRIPS. Bus strips are generally use to provide power supply and socket strips are used to hold components . 

 

PROJECT_1- TESTING LED ON BREAD BOARD

Here in this project we will glow a LED with a 9V battery using breadboard.

Things we need

1LED

1 resistor 1k

1 9v battery

And our breadboard

                                    

 We will implement this circuit on bread board

  

To implement this circuit make bread board connection like this and if connections are fine LED will glow ,If not then check connection once again and check battery also.

PROJECT_2- LED BLINKING PROJECT

This time we will something big , A blinking LED project using NE 555 IC.

Things we need

1 LED

1 CAPACITOR 10uF

RESISTORS 1X 1K, 1X 1OK, 1X 15K

NE555 IC

1 9v battery

And BREADBOARD

                                       Actually we will implement this circuit on breadboard

                                        To do it just make breadboard connections like this

If everything is fine LED will start blinking.

              

So we have learnt how to use a breadboard for making electronic circuit. We can implement very huge circuits on breadboard too. If you have any doubt, questions , comments leave them in our comment box.
