At the end of this chapter, and hence the end of the contextual part of the book, you should be able to develop your own Internet of Things projects. In this chapter, we used a commercial IoT cloud platform to handle your sensor data. We also deployed a cloud instance to host open source IoT tools and created our own version of the customized IoT cloud platform. Certainly, the content that you learned is not sufficient to develop scalable and fully-stacked commercial products, but it is really helpful to get you started with them. In a large number of cases, this material is sufficient to develop DIY projects and product prototypes that will ultimately lead you to the final product. In the next two chapters, we will put the material that we learned to the test and develop two complete IoT hardware projects. We are also going to learn a project development methodology that is specific to hardware-based IoT products, which can be applied to convert your prototypes into real products...
