You’ve covered a lot of material in this chapter, but you haven’t exhausted any of the topics presented. Perhaps you’ve gained some perspective on what it takes to design and deploy a successful robot project. And maybe robots just aren’t your thing. Any of the particular problems addressed in this robotics-oriented chapter can also be used in numerous other fields and other, non-robotic projects. Either way, it’s good to know the sorts of amazing things you can do with your simple Arduino, once you’ve had a chance to take a look at its internals.
Good luck with your Arduino projects! Remember to have some fun along the way.
