Hacking with Sensors

Chapters 6, 7, and 8 all overlap somewhat, as many sensors are also modules and both can often be used with an Arduino.

In this chapter, we will look at how to use a range of sensors, whether with a little supporting electronics or as an input to an Arduino, or sometimes both.
