Internet of Things Programming Projects

Understanding the Raspberry Pi

Welcome to the wonderful world of Internet of Things (IoT) projects and the Raspberry Pi in this, the second edition of Internet of Things Programming Projects.

In this book, we will take a journey into IoT projects using the Raspberry Pi. In the first part of this book, we’ll explore IoT projects on the Raspberry Pi, initially transforming it into a weather station with the Sense HAT to capture real-time data. Later, we’ll use motors and general-purpose input/output (GPIO) pins to repurpose the Pi as an analog metering device.

We will then create an IoT home security system, using the Raspberry Pi as the central hub for an alarm system. We’ll also develop a LoRa-enabled IoT monitoring station for remote sensing. The book culminates with our most ambitious project: building an IoT robot car powered by the Raspberry Pi.

We will start this chapter by exploring the various Raspberry Pi models and their significance, observing...

Technical requirements

The following are required to complete this chapter:

  • Late-model Raspberry Pi, such as the Raspberry Pi 5 4/8 GB model or Raspberry Pi 4B 4/8 GB model
  • Keyboard, mouse, and monitor
  • Raspberry Pi Sense HAT is optional but encouraged; we will be making use of the Sense HAT software emulator

The GitHub repository for the chapter is located at https://github.com/PacktPublishing/-Internet-of-Things-Programming-Projects-2nd-Edition/tree/main/Chapter1.

For those that have access to a 3D printer or 3D printing service, there are .stl files available in the Build Files directory of this chapter’s GitHub repository for the construction of the optional custom case. Files are available for the Raspberry Pi 5 and Raspberry Pi 4B versions of the case.

A general knowledge of programming is also required. We will be using the Python programming language in this book. We will start with basic code and work our way toward more advanced coding as...

Exploring Raspberry Pi models

Every Raspberry Pi model, from the initial Raspberry Pi 1 to the current Raspberry Pi 5 and the compact Pi Zero, possesses distinct characteristics and functionalities that make it an exciting choice for IoT developers. Each model excels in different areas, such as processing power, size, and energy efficiency.

The Raspberry Pi models have evolved significantly over time, with each iteration bringing notable advancements in processing power, memory, and capabilities.
