The world around you is analog. Even though you might hear that the world is “going digital,” the majority of observable features in your environment will always be analog in nature. The world can assume an infinite number of potential states, whether you are considering the color of sunlight, the temperature of the ocean, or the concentration of contaminants in the air. This chapter focuses on developing techniques for discretizing these infinite possibilities into palatable digital values that can be analyzed with a microcontroller system like the Arduino.
In this chapter, you will learn about the differences between analog and digital signals and how to convert between the two, as well as a handful of the analog sensors that you can interface with your Arduino. Using skills that you acquired in the preceding chapter, you will add light sensors ...
