A breadboard is used to quickly prototype electrical circuits without having to solder so they can be reused.
How Do They Work?
A breadboard is a container with a lot of holes, which have rows of metal strips underneath. When you insert a wire or pin into it, it will make contact with the metal strip. This will then cause it to become electronically connected to all other components in that row.
Breadboard Layout
A breadboard is usually contains two main areas:
Component Connector Strips: These are in the middle of breadboard and are used to connect components together. Each row (usually containing 5 holes) is connected internally. Often times the board contains two sets of rows, with a groove separating them.
Power Rails: These can be found along the edges of the breadboard and are used for distributing power (positive and ground) to all the components. These strips are internally connected vertically across the entire length of the breadboard, making them convenient for delivering power to multiple components.
