Introduction 

The breadboard derives its name from an early form of point-to-point construction. In the early days of radio, amateurs would nail copper wire or terminal strips to a wooden board (often literally a board for cutting bread), and solder electronic components to them. It is typically used used to make up temporary circuits for testing or to try out an idea. A picture of the breadboard that  we will use is shown at the bottom of the picture on the right. It is connected to a power supply at the top. As shown below, the power (+ and -) can be futher connected to the components by wire strips. No soldering is required so it is easy to change connections and replace components. Parts will not be damaged so they will be available to re-use afterwards.
