Internet of Things Programming Projects: Build modern IoT solutions with the Raspberry Pi 3 and Python

Connected devices become easier to understand when you build them one piece at a time. In Internet of Things Programming Projects, Colin Dow pairs the Raspberry Pi 3 with Python to show how code can interact with sensors, motors, web services, and everyday hardware.

The projects progress from getting a Raspberry Pi ready and writing Python programs to creating connected devices with practical uses. Along the way, the book makes the link between software and electronics tangible: a program can retrieve weather information, respond to sensor input, or help control a physical device.

Start with the Raspberry Pi and Python

The opening chapters establish the working foundations: setting up Raspbian, choosing Python tools, writing programs, and using the Pi’s GPIO pins to communicate with the outside world. Coverage of libraries and circuit-building introduces the hardware side alongside the code, giving readers context for the projects that follow.

Turn data into something you can see

One of the book’s distinctive threads is the use of web-sourced weather data to drive an analog indicator. The project brings together a web service, Python, and servo control, showing how information gathered online can produce a visible response in the physical world.

Build connected projects, step by step

• Work with Raspberry Pi GPIO and sensor data.
• Use Python to control a servo motor and other connected components.
• Create a Raspberry Pi web server and a weather dashboard.
• Develop a home-security dashboard and a connected doorbell.
• Explore the components of a Raspberry Pi robot car and connect its inputs and controls to web services.

Where software meets the physical world

Rather than keeping programming and electronics in separate boxes, these projects bring them together. Readers can follow how code, data, and hardware interact, while the chapter-by-chapter format offers a practical route through the subject for Raspberry Pi makers and learners developing their Python skills.

If you want to understand IoT by building and connecting real components, this book offers a hands-on starting point with Raspberry Pi 3 and Python.
