Abstract
In Chapter 17, we learned how to use RC (resistor-capacitor) circuits to create timers. In this chapter, we are going to use our concept of timing circuits to move from one-time timer circuits to oscillating circuits.

Notes
- 1.
You can build an oscillator with more than two states, but we won’t be concerned with those circuits in this book, though the setup is similar.
- 2.
Since most pins are activated by a higher voltage, pins that are activated with a lower voltage get the special designator.
- 3.
For most of our uses of the NE555, you can actually leave pin 5 unconnected—our usage of the chip is not so precise or power-hungry as to be affected in this way. Nonetheless, I show it connected so that you can see how it is supposed to be connected.
