Arduino battery connection schematic What’s Next? Now you have built your first prototype with the Arduino. Next, we will present one possible way to create an enclosure for the Stalker Guard. The proposed enclosure methods will give you suggestions on how to construct devices until the prototyping phase. Devices functioning on a prototyping breadboard do not necessarily make a major impression, except maybe on the most die-hard geeks. If your fingers are already itching to start building the next project, you can skip the enclosure stage and move on to the Robot Insect in Chapter 4.
