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.

Interfacing a CO2 sensor with the Pico

In this section, we will discuss interfacing the CO2 sensor with the Raspberry Pi Pico. This section is meant for those who don't have access to a local data source for air quality. The SCD30 sensor has a measurement range of 400–10,000 ppm. We chose this sensor because it comes with an onboard temperature sensor that provides temperature compensation to the CO2 concentration calculation. The datasheet for the sensor is available from here: https://bit.ly/3tyJZ9C. We will measure the CO2 concentration and publish it to ThingSpeak, a service we discussed in Chapter 4, Fun with Gardening!. This will enable us to share a public dashboard of the local air quality levels.

If you have access to a public data source, you are welcome to skip this section and move to the next section where we test the motors.

We are assuming that you have installed the required libraries to communicate with the sensor using the instructions from earlier...
