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.
 What is a Bread Board ?
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|

 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 mm
1 mil => 0.001 Inch => 0.00254 cm => 0.025 mmAlso:
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.
In this case, one end of each resistor is pushed into the solder less breadboard, while the other end of each resistor has a wire soldered to it. The other end of the wire connects to the appropriate LED segment.
Easy way to connect the common CR2032 Battery needed for RTC or even MSP430.
Instructable that you can build your self.
Commercial ones are also available from: Adafruit, Seeedstudio, Sparkfun
Instructable we have great ease in our prototyping efforts.
