Chapter 5 of Getting Started with Arduino is "Advanced Input and Output." The topics covered in this chapter are:
- Analogue input and output to allow continuous (or at least many-valued) values as opposed to just digital on/off
- The use of a photoelectric sensor to provide continuous input and an LED to provide continuous output
- Serial communication to permit data exchange between different programs and different hardware
All of this is really used to lay the groundwork for the extended example in Chapter 6. And this is where I have my first movie examples to show things changing gradually. (Always glad to have the iPhone handy....)
