Introduction: The BREADBOARD

About: Electronics Engineer | Build, Automate, Innovate | I'm a Maker :-)

This Instructable explains about the basics of a Breadboard and its uses.
I have divided this into two parts. :

1) The Basics and various types ( which are covered in the above video which i made for a fast go-through)

2) How to use it ? ( covered in the instructable)

I would advise you to go through the above video first. Its a very short video covering the basics of a breadboard. This Instructable is a continuity of the above video.

And, if you don't have your own breadboard then get it from the following links.

1) Normal Breadboard : From Filpkart

2) Mini Breadboard (2pcs) : From Filpkart

So, Lets Start It !!!

Step 1: How to Use It ???

Thinking of what we can do with a breadboard and how ?? Then you are at the right place.

A Breadboard can be used in many different ways according to what you imagination & creation ability is...... :-p

The holes on a Breadboard are used to insert the leads of various electronic components in it. Also we can insert wires in it for input / output / connections / power supply purposes / etc.

The terminal strips generally define the area in which we must place our electronic components of a circuit.

The Bus strips are generally use to provide supply to the circuit from a power supply or form a battery.

Few points to keep in mind :-

1) The terminals of any component must be inserted in two holes of different terminal strips. If you place the component in the holes of same terminal strip, then you will short the terminals of the component (it's like you placed nothing).

2) The components that are connected to each other have their common terminals in the same terminal strip. This make a connection between their terminals.

3) If a component with common connections with other components has no place to fit in a terminal strip, then place the component in some terminal strips and make connections using wires to the component.

4) Depending upon the layout of your breadboard you must provide power supply connections to the circuit. If your bus strips are disconnected form each other than connect them using wires (from one strip to another).

5) For breadboard use a single stranded to make connections, it will make the insertion of wires easier.

Let's insert our first component into the bread board !!!

Step 2: Place Them !!!

The 1st first image shows the insertion of a LED into the breadboard. The anode and cathode terminals of the LED are placed in two different terminal strips in order to ensure proper working of the LED.

The 2nd image shows three resistors connected in series on the breadboard. The common / connected terminals between two resistors are inserted in a common terminal strip. The effective resistance is observed between the first terminal of first resistor and the second terminal of the third resistor.

The 3rd image shows three resistors connected in parallel on the breadboard. All the resistors have their one terminal inserted in the same terminal strip as same for other terminal too. The effective resistance is observed between these two terminal strips.

The 4th image show a MOSFET placed on the breadboard. The all terminals of the MOSFET are inserted in each separate terminal strip, to ensure their separation from each other. Any transistor, mosfet, voltage regulator, etc, must be placed in such format (every terminal in a separate terminal strip).

The 5th image shows the placement of an IC (integrated circuit) on the breadboard. While placing any IC of such a package, it must be always placed in such way. Observe that the one side of legs of the IC are inserted in half part of the breadboard and the legs on either side are inserted in the other half of breadboard. This allows a separate terminal strip to be used for each unique pin of the IC. The packages that can be placed on the breadboard are discussed in the further steps.

The 6th image shows the parallel way of placing components on the breadboard. Observe that there's one capacitor which is placed in parallel with the first two terminals of the transistor.

The 7th image shows another way of connecting two components (resistor in this case) in series by means of connecting wire (single stranded). The wire is used to connect the common terminals of the both resistors. Observe that each terminal of the each resistor is in a unique terminal strip. This method must be used when components are far away from each other or there's no place in a terminal strip to insert any new component.

The 8th image shows another way of using the above mentioned method. The above method uses a single stranded wire to connect the terminal strips. But, here a Male to Male Jumper Wire is used to connect the two terminals strips to each other in which the jumper wire is inserted.

The 9th image shows the insertion of Arduino Nano (micro-controller board) on the breadboard. It is similar to the insertion of an IC on the breadboard.

After all these, the ultimate of position of the components depends on the circuit diagram. So, do refer the circuit diagram properly while placing every component on the breadboard. And recheck every circuit path after you finish placing and connecting your components on the breadboard before Powering it Up !!!

Step 3: Adding a Power Source !!!

Every circuit you make on a breadboard, requires a proper power source to make the circuit work. For this connect the Vcc and GND terminals of your circuit to separate Bus strips with the help of connecting wires.

But the proper voltage required for your circuit must be determined first before going further. Once you get the proper details, then choose a power source accordingly. Always remember to find the maximum and the minimum voltage rating of the supply voltage to the circuit.

The power supply which ever you choose must provide the voltage output which falls in between the minimum and maximum voltage ratings of your circuit.

They are various methods of adding a power source to your breadboard. Some of them are:

1) Using a 9V battery : Here, in this method, you can insert a 9v battery clip into the bus strips of the breadboard and connect it directly to the circuit or regulate it using a proper voltage regulator circuit and then supply it to the circuit.

2) Using External Variable Power supply / Bench or Lab Power Supply: Extend two separate wires from the Bus strips in which you have connected the Vcc and GND terminals of your circuit.

3) Using a On-board 5V/3.3V regulated supply module : This type of supply is a new way of providing regulated / variable supply to your breadboard. This method uses a power supply module which fits on the bus strips of your bread board and provides a well regulated power supply to your circuit from a DC wall adapter. This method is mainly used for the circuits running on 5V and 3.3V as the module gives these output voltages only. You can also get adjustable version of such a module in the market (or make one on your own !!!). You can buy the 5V/3.3V power supply board from here : From Filpkart

Step 4: Supported IC Packages for Your Breadboard

Some general IC packages that can fit on your breadboard are :

1) SIP Package

2) DIP Package

3) TO-92 package

4) TO-126 Package

5) TO-220 package

These are a few packages which can easily fit on any breadboard. Check out the above images. So next time you buy an IC, do check the type of IC package you buy.

Gently, pushing them over the holes of the breadboard places them on breadboard. Sometimes, if for any IC, itS is difficult to be inserted into the breadboard, then please check the alignment of every pin of the IC and the breadboard holes. They should match properly with each other. You can also try pushing the IC by applying a little pressure to insert it, if it is properly aligned with the breadboard holes.

Step 5: Finishing It !!!

Well, that's all about the Breadboard...

The basics of Breadboard can be ended-up here.
