We have all used breadboards, or those who plan to jump into the fascinating world of electronics need to know about them. This article focuses on introducing breadboards inside out, to help people use them and prototype their innovations faster. We would walk through Bread board concepts, connecting various chips & devices, efficient prototyping and documenting the designs.
Bread Board or more precisely Solder-less Bread Board is one of the essential tools for any one stating with electronics or microcontrollers. It is useful for both Pro’s and beginners alike. Here are pictures of the different breadboards that one can find.
|Older Variety widely available in Bharat(India)|
|Newer Variety slightly Costly in Bharat(India)|
|Smaller ones (Half Size) available from Adafruit|
|Oldest form of Bread boards (Not available now)|
|More recent Transparent Fancy bread board from Sparkfun|
Apart from the above breadboards are also available in kit form. Which include optional Power supply Connections and other connectivity options.

 General know how on Length Units used in Electronics.
Going forward in this tutorial it is important to note that we would be using a particular unit a lot of times “mil” or also popularly known as “TH”. It is 1000th of an Inch. Here is a conversion table that might come in Handy.
1 Inch => 1000 mil => 2.54 cm => 25.4 mm1 mil => 0.001 Inch => 0.00254 cm => 0.025 mm
1 mm => 0.1 cm => 39.37 mil=> 0.03937 Inch
It is important to know this conversion as most of the Printed Circuit Board unit are in “mil” and the data-sheet units are in “mm”. There has always been a classical fight between the more accurate one. However most of the things in PCB arena are still in “mil” and using mm means using 4-6 decimal precision in the current boards.
Thus we prefer to use the “mil” unit more than mm. However we would try to provide a proper conversion available for the parts that have been measured. There is a handy converter available in the blog which can convert in any direction either “mil” to mm or vise-versa.
Bread Board Dimensions and Differences.
In general any bread board is fine for starting.
However there are some small caveats that we need to be aware. We would try to explain some
