A Breadboard is a rectangular plastic board with a bunch of tiny holes in it. These holes let you easily insert electronic components to prototype (meaning to build and test an early version of) an electronic circuit, like this one with a battery, switch, resistor, and an LED (light-emitting diode). 

The leads can fit into the Breadboard because the inside of a Breadboard is made up of rows of tiny metal clips. This is what the clips look like when they are removed from a Breadboard.

Features : 

Completely reusable good for experimenting with electronics reduce the time of trial than soldering directly and damaging the componant 

the best choice for student and hobbyist alike .

ABS Plastic material

Coordinates for easy component placement

Phosphor bronze nickel plated spring clips

Accepts a variety of wire sizes (20-29 AWG)

This tutorial shows you how to use a solderless Breadboard to build an electronic circuit, including the basics of how a Breadboard works and some common mistakes that beginners tend to make:
