Explanation Of Breadboard, Front And Back Panel Of Breadboard

In order to build a circuit, we have to connect circuit components together, and a great tool for this purpose is the solderless breadboard. Now, probability you already got it as part of the arduino starter kit so just check. A breadboard is a simple prototyping plastic base board that easily allows us to wire up. Simple circuits without having to solder together parts to a custom printed circuit board.

They come in many sizes, shapes and colors. It is important to understand how breadboard works so that we can use them more effectively in our projects the key to using a breadboard is knowing how the sockets are connected and this is what i am going to explain.

First, looking on the blue and red lines on the left side that run horizontally the pins that are part of those lines are designed to be used as power and ground buses.

Now looking on the picture on the right side, this is the back panel, all the red pins are electrically connected in the back panel and are used for providing power, meaning 5v. All the blue pins are also electrically connected and are used for the ground connection, because we’ll need to connect a circuit/external components to the supply voltage and ground.

These long horizontal lines of many holes are useful for providing supply voltage and ground to those external components.. Moving on, all the vertically aligned pins are also connected in rows, with a division in the middle to make it easy to mount some integrated circuits on the breadboard.

If i will paint on the screen. Let me add some pointer. Ok, so this line is used for ground. This line is used for power. All those holes are connected, that's the backend view, and that's the frond end. Now if i will connect some component, like a resistor, the way to do that is to connect it from here to another location, because column number 2 and column number 6 are not connected, but all holes in column number 2 are connected to each other

It's connected as one bus, so i will take another component and connect it to this point and take it for example over here, then what what i got is that those two, this one and this one are actually connected. In column 6, as i said the all colum is connected at the backend, and this is the way to connect between components, and in addition, i can choose to connect this element ot the ground by taking this hole and connected that over here.

I just connected that to the ground and i can take this component and connect it to the power. I just created a circuit and this is the way to created all kind of circuits using the breadboard. If i will take some integrated circuit then the ic will like a box and all the pins will be align connted to those holes in both sides, that's the why to connect some ic, and then if i would like to connect to some pin location, let's assume i need to connect.

This pin to the power, so i would just take this hole and connect that to the power that's the way to connect things and i will use that allot.

Looking on some simple circuit example, we are taking ground and voltage power from the arduino board to the breadboard. In addition we can also connect the lines below to the ground and power to extend the available places to connect power and ground. Next, we have the led, one side is connected to the ground side and the other side is connect in serial to a resistor.

That is connected to the digital pin #3. In that case we got a simple circuit, arduino, led and some resistor. Now some small remark, if you lack the fundamental understanding of electronics circuit,. Like, what is a voltage, or power, what is resistance or current, what is a circuit and so on.

I strongly recommend to review my previous course that is called “the theory behind electronics”. That will provide you some fundamental knowledge about electronics. Please watch this video below to understand practically and better.
