Prototyping
Prototyping is a way to quickly realize a circuit and to see if it will work or not. By prototyping a thing, we can build something without spending a lot of time and money wiring everything up from scratch. This is great for focusing our efforts and our ideas rather than getting lost in soldering wires from one component to another. One of the best things that we can use to help make prototyping even easier is a breadboard.
Breadboards
Historically, amateur radio builders would put together circuits using wires and nails quite literally on cutting boards for bread. Today, we use the solderless breadboard, shown in Figure 12-12, to quickly prototype a circuit.
