Now that we have all the deployments of our code for the backend cloud services, it’s time to dive into the Raspberry Pi (Pi) device itself. This next set of the book will all revolve around coding to the Raspberry Pi device. We will perform a variety of coding tasks on the Raspberry Pi mostly using libraries, some going bare metal. Much of this is to give a glimpse of how we can create a connected environment between device, cloud, and user.
