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.

Interfacing a Bluetooth Low Energy module

In this section, we will discuss interfacing the Adafruit Bluefruit LE SPI Friend (hereby referred to as the Bluetooth module) to the Raspberry Pi Pico.

In case you are not familiar with Bluetooth Low Energy technology, it is a low-power wireless network technology meant for wireless sensors and other peripherals that can run off a coin cell. You can learn more about Bluetooth Low Energy (BLE) from this tutorial: https://bit.ly/3BkLPNu.

The breakout board used in this section comes with a Raytac MDBT40 BLE module, which is FCC and CE certified. In case you are not familiar with FCC and CE certification, they are mandatory certifications of approval for use in the United States and Europe respectively. The module is designed around the Nordic nRF51822 chipset. The folks at Adafruit implemented firmware that enables you to interface a Bluetooth module as a peripheral in your project.
