What is a breadboard?
A breadboard is a simple device in which you can create electronic circuits without soldering. It is a rectangular shape plastic board with a bunch of tiny holes in it.
In these holes, you can easily insert electronic components (like LED, Capacitor, Resistor, Diode, different IC, etc) and test the circuit which you have made.
In this board, there is no permanent connection so there is an advantage to remove components if you make a mistake. So it is very useful for beginners who are new in electronics.
Breadboard connections
When you uncovered the backing layer of the breadboard then you can see lots of vertical and horizontal rows of metal strips.
These metal strips have little clips at the top and hide under the plastic holes. When you insert component's leads into a breadboard hole these clips help to hold the lead.
It is notable that there are only five clips on the top of the strips. So you can only have up to five components connected in one particular section of the breadboard.
How are the holes connected?
What do the letters and numbers on the breadboard mean?
The intersection of rows number and columns letter gives an individual identity of holes. For example, a hole called "B10" means where column B intersects the row 10.
And also there are long strips on the side of the breadboard. These strips are typically drawn by red and blue (or black) lines with plus(+) and (-) signs, respectively.
These lines referred to as power rails, and they are used to supply electrical power to the circuits from a battery or other external power supply.
Types of Breadboard
And the numbers of holes in the mini breadboard are 170 because in the mini breadboard there are no power rails. Mini breadboards have come in different colors.
How to use a breadboard?
Now we are going to learn how to use a breadboard. Here I am going to show you how to set a very simple circuit on the breadboard.
If you have seen the inside connection of the breadboard then you can understand it very easily. To learn the use of breadboard we follow some steps.
Step 1: At first, draw a circuit on the paper
You can draw a circuit on the paper and then set it on the breadboard very easily. Here I am using a simple circuit to make it simple. To make the circuit the using components are
Step 2: Insert the components on the breadboard
After connecting the battery takes an LED and put one lead in C3 and another lead in C5. Take a resistor of 100ohm and put one lead in D5 and another lead in F5 which is connected in series with the LED.
Now take a push-button switch and put two leads in row 5 which is connected in series with the resistor and another two leads in row 7. At last, take a connection from row 7 and put it in the ground.
If the LED is not glowing then there is a problem in connections then shake the components or clean the wire and put it again.
