Raspberry Pi Pico DIY Workshop

By: Sai Yamanoor, Srihari Yamanoor

Overview of this book

The Raspberry Pi Pico is the latest addition to the Raspberry Pi family of products. Introduced by the Raspberry Pi Foundation, based on their RP2040 chip, it is a tiny, fast microcontroller that packs enough punch to power an extensive range of applications. Raspberry Pi Pico DIY Workshop will help you get started with your own Pico and leverage its features to develop innovative products. This book begins with an introduction to the Raspberry Pi Pico, giving you a thorough understanding of the RP2040's peripherals and different development boards for the Pico designed and manufactured by various organizations. You'll explore add-on hardware and programming language options available for the Pico. Next, you'll focus on practical skills, starting with a simple LED blinking project and building up to a giant seven-segment display, while working with application examples such as citizen science displays, digital health, and robots. You'll also work on exciting projects around gardening, building a weather station, tracking air quality, hacking your personal health, and building a robot, along with discovering tips and tricks to give you the confidence needed to make the best use of RP2040. By the end of this Raspberry Pi book, you'll have built a solid foundation in product development using the RP2040, acquired a skillset crucial for embedded device development, and have a robot that you built yourself.

Chapter 7: Designing a Visual Aid for Tracking Air Quality

In the previous chapter, we built a visual aid containing a giant seven-segment display to track physical activity. In this chapter, we are going to build a visual aid that can serve as an interactive exhibit to track air quality. By the end of this chapter, you will be able to build something like the one shown in the following figure.

Figure 7.1 – Air quality exhibit

The goal of this project is to educate people about air quality in our immediate surroundings. We will discuss the project in two different ways. In the first approach, we will build the display using publicly available data sources. In the second approach, we will discuss building it using a carbon dioxide sensor that is interfaced with the Raspberry Pi Pico.

The topics discussed in this chapter include the following:

  • Inspiration for the project
  • Installing requisite libraries
  • Using public data sources for air...
