Before I get into the fascinating topic of integrated circuit chips (often referred to as ICs or simply chips), I have to mention that some of the things I asked you to do in previous experiments could have been done more quickly if you had used chips.
Does this mean you have been wasting your time? No, absolutely not, because you still need to know how resistors, capacitors, and transistors interact with each other. These basic parts, properly known as discrete components, will continue to be used in circuits throughout the rest of the book.
Chips can simplify circuits, though, and can be addictive to play with, although you may not become quite as excited as the character in Figure 15-1.
Figure 15-1. My role model. ...
