Although the individual components and integrated circuits discussed in Chapters 3 through 7 form the A-team when it comes to shaping the flow of electrons in electronic circuits, there are a bunch of other contributing parts that the A-team relies on to help get the job done.
Some of these other parts — such as wires, connectors, and batteries — are essential ingredients in any electronic circuit. After all, you’d be hard-pressed to build an electronic circuit without wires to connect things together or a source of power to make things run. As for the other parts we discuss in this chapter, you may use them only now and then for certain circuits. For example, when you need to make some noise, a buzzer sure comes in handy — but you may ...
