Arduino Basics - solderless electronic Breadboards

Let us look at the currently available commonly used breadboards here in India. You can see in the above image four breadboards of different sizes. The bigger ones are of Full size, the one on the left is Half size, the one at the top left corner is the Mini size.

If you ever wonder how the pins or clips of the breadboard are arranged, imagine a branch of coconut and see how it's leaves are arranged.

Exactly this is how the clips in a breadboard are arranged.

Above you can see a full breadboard from the back side, with the sticker removed. I have sticked a transparent sheet of acrylic so we can see through. 

If you can remember this placement of the breadboard clips you should not have any difficulty in determining which two points on a breadboard are connected. 

There are eight clips four on wither side used as power lanes. They may appear as two lanes at each side, but depending on the breadboard you purchase they may be four or eight. If your breadboard is marked by Red and Blue lines, then the continuity of the lines will indicate the span of the clip. In this case both the Full breadboards displayed above have four lanes on either side. 

If you ever wonder about the span of the power lanes on your breadboard then use the Continuity Tester of a multimeter to see which segments of your power lanes are connected to each other. 

It is like having two Half sized breadboards connected to each other in a column. Mini breadboard shown here does not have power lanes.


All the breadboards shown here have a adhesive sticker at the back. It is covered with a removable cover. You can remove this cover when you want to stick the breadboard onto something. If you want you can remove the glue sticker also. But then you will need a synthetic glue to stick it on another surface. I have used it to stick my breadboard on a transparent acrylic sheet. I used an industrial grade Synthetic Resin Instant Adhesive.  You should be able to find one easily in any Hardware store in India.
