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.

Installing the requisite libraries

We are going to install all the libraries required for this chapter. The first step is to download the CircuitPython Library Bundle. You can download the Library Bundle as a ZIP file from here: https://circuitpython.org/libraries.

Extract the contents of the ZIP file to get started with the library installation.

CircuitPython Installation

We are assuming that you have installed CircuitPython on your Pico. If you are not familiar with the installation process, we recommend following the installation process from Chapter 1, Getting Started with Raspberry Pi Pico.

The AM2315 sensor

We need two libraries for the AM2315 temperature (shown in the following figure) and humidity sensor, namely adafruit_bus_device and adafruit_ahtx0. In the extracted bundle, there is a folder called adafruit_bus_device along with the adafruit_ahtx0.mpy file. Copy over the folder to the lib folder of the Pico.
