Breadboard... lets get practical

What actually a Breadboard is ????

1. Its a construction base for prototyping electronics circuit & models

2. In breadboard the circuits are temporary arranged  for testing  purpose

3. Its simply a solder-less board , you don't need to solder the electronics component 

4. In this tutorial we will learn how to use a breadboard  

fig.1 - This is how a actual breadboard look like

Now lets start our tutorial , first of all collect the following items at your work space along with your

breadboard

1. Hook wire :-  You can easily get this wire in electronics shops around you, we will use this wire for 

                         bread board connections 

fig.2-hook up wires

2. Wire stripper :- In a simple way a stripper is a sort of wire cutter it is used to strip the insulating

                                plastic of the hook wire with a perfection & ease

3. Battery, 9v :- A   9 volt battery for power supply of breadboard

fig.4- 9 volt battery

4. Battery cap :-  Its  basically a connector for standard size 9v battery with two wires 

                                  red wire  -  v cc

                                 black wire- ground

5.Miscellaneous:-  some basic electronics component like Led's , IC, in this tutorial we will learn how to 

                                do breadboard connections step by step and some basic concept of electronics

                                collect all the Items at your work station

   This is our bread board let us explore it from inside that how the connections and arrangement is
         done inside the bread board 

We can understand it with the help of diagram given below

 so here we can see that here are two railings of blue & red color on both side they are meant 

for power supply of the bread board the outer most railing is take as a positive & inner most railing  

take as negative  (for our ease as in diagram it is given different)

we consider red as positive & black wire as negative

so let's start the connection

Step 1.

Arrange and hook the wire as given below the image for supply power to the whole breadboard

followed by this connection here we can see we have connected two more connection in between the breadboard as in breadboard after five block of power railing there is a break to join this break we connect this arrangement like this

Step:2 Check the electronic component with the help of multimeter

• we can check that our LED is working fine or not
• value of resistence
• voltage of battery
• continuity of circuit

Step-3 :- Try this circuit diagram on bread board

• you can take help from the below image if you want either do it with yourself

 step 4:- This is how we have to connect the battery and battery cap

 step 5: -Try this circuit diagram on bread board

step 6: - Just like that try led in series put 3 Led in series without Resistance 

so this is the tutorial for breadboard hope it will help you

(Note:- led need needs only 2 to 2.5 volt for switching , so always connect a single Led with 1 k resistance ,as 9 v will damage LED if connected without resistance )

Project:-

Now let us make a project of simple torch light with 12 LED  it consists of both series and  parallel connection

• The circuit diagram is given below

•  I have made it on dotted PCB you can try it own your bread board after that implement it on dotted PCB 

Hope you like it all , in next basic electronics post I will explain about touch sensor
