Breadboard (solderless breadboard) is a great way to construct electronic projects easily and in less time without the need of soldering. You can use breadboards to make all sorts of fun electronics projects. 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 an electronic circuit. It is easy to remove a component if you make a mistake, or just start over and do a new project. Extra jumper wires are used to make connections.
