From components to circuits
In the early days of electronics, a circuit was built by bolting or screwing the components to a chassis of sheet aluminium or wood and then joining their terminals by stout cotton-covered copper wire. A gradual reduction in the average size of components, plus the need for mass production has led to this technique being totally replaced by those described in this chapter.
Breadboard
A breadboard (sometimes called a plugblock) is used for building temporary circuits. It is useful to designers because it allows components to be removed and replaced easily. It is useful to the person who wants to build a circuit to demonstrate its action, then to reuse the components in another circuit.
A breadboard consists of plastic ...
