A quick tour on breadboard


Bread Board is a great tool to design and test your circuits. You do not need to solder wires and components to make a circuit while using a bread board. It is easier to mount components & reuse them. Since, components are not soldered you can change your circuit design at any point without any hassle.

Structure of a Bread Board: Basically, a bread board is an array of conductive metal clips encased in a box made of white ABS plastic, where each clip is insulated with another clips. There are a number of holes on the plastic box, arranged in a particular fashion. A typical bread board layout consists of two types of region also called strips. Bus strips and socket strips. Bus strips are usually used to provide power supply to the circuit. It consists of two columns, one for power voltage and other for ground.
Socket strips are used to hold most of the components in a circuit. Generally it consists of two sections each with 5 rows and 64 columns. Every column is electrically connected from inside



The breadboard above is a single panel with two attached "bus strips." The second picture gives a little more detail. The green lines represent the internal connections of the breadboard. The bus strips on this breadboard are labeled + and - and are used for power. They run the length of the breadboard. Also, notice that the way that they are arranged, the inside edges of each bus strip is opposite polarity. This really helps when working with standard logic and most other ICs.The middle area is the component area, and this is where you will work your electronic magic.

Inside the Breadboard :

On some breaboards, the bus strips may be broken at the middle (Usually between row 31 and 33.) This splits your bus strips into 4 separate strips. This is useful if you are working with more than one voltage on your breadboard. If you need only one supply voltage on your circuit, then you should add a jumper across this gap to reconnect the bus strips.

 

Types of Breadboard :

1.Most commonly used one.

2.Breadboard with built-in power supply.

 This particular breadboard is no longer made. It has a +5V fixed supply capable of 1A, and a +- 15V supply. It also has two digital switches and two momentary switches connected to flip-flops. Lastly, it has two LEDs with current limiting resistors. If you are interested in getting a breadboard like this (or maybe something more modern) check eBay or google for "Powered Breadboard" or "Powered Protoboard."
