Chapter 5. Basic Electronics

In “Experiment: Controlling an LED”, you were launched right into controlling a motor using a transistor, without any real explanation as to how this worked. If you already know a little about electronics, you might well be familiar with transistors and be able to skip much of this chapter. If, on the other hand, you are new to electronics, you will find this explanation helpful.

Current, Voltage, and Resistance

In this section, you will need to refer to the schematic diagram for “Experiment: Controlling a Motor” that you built on the breadboard. This is shown in Figure 5-1.
