Making an Enclosure

In this project, you will build a Stalker Guard (Figure 3-1), a simple alarm device that measures the distances of objects behind you and vibrates when something comes too close (see Figure 3-2). You will also learn a program you can easily modify for other projects that works by monitoring data sent by a sensor and reacting when specific conditions are filled.

Over the course of this project, you will learn the basics of Arduino programming, distance measurement ...
