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.
18.1 Oscillation Basics
So far, most of the circuits we have made have been fairly directional. You do an action (i.e., press a button) and then something happens, but then the circuit just maintains a steady state after that. In Chapter 17, we at least added a delay—allowing the circuit to do something later.
However, if you want actions to continue on into ...
