Arduino Beginner Series: The what and how of a Breadboard

Hello everyone!! Welcome to this post on Arduino!! Since this is a beginner series we’ll deal with super simple (but super exciting!!) projects! I would Love to hear from you guys so be sure to post your doubts, queries and experience about this project in the comments!
Need a short introduction to what the Arduino is? Then click on LINK

Knowledge of breadboards is indispensable while working on the Arduino.
In this post, we shall talk about what a breadboard is, why is it called so, and also where and how to use it.

What is a breadboard?

The breadboard is an electronic circuit builder used for prototyping without the need to solder your components together.

Why call it breadboard?

Many years ago, when electronics were big and bulky, people would grab their mom’s breadboard, a few nails or thumbtacks, and start connecting wires onto the board to give themselves a platform on which to build their circuits. So engineers took that concept to the next level and decided to come up with the electric circuit builder solderless boards: breadboards.

How does it work?

So with reference to the image alongside, the red and black lines along the longer side of the breadboard are known as the power rails. In the holes of these lines you can plug your microcontroller or power supply to provide power to the components.

The blue lines perpendicular to the power rails are called component rails. The holes along these lines are used to plug-in the components.

The important thing here is that the 5 holes on the blue component lines (with reference to above image) are all connected and are at the same potential. But the holes on two different blue lines are not be connected.

The backside of a breadboard

Along the centre of breadboard there is a trench. And the rows on either side of the trench are not connected together.

You guys should check this video out! It gives a clear cut explation and helped me to understand the working of the breadboard

So that’s all you really need to know as a beginner. Anyway get building!!
Exciting projects coming up in the next post!
