To get the most out of this book
The projects discussed in this chapter are hardware intensive. In order to maintain consistency, we used the Raspberry Pi Pico across all chapters. You will also need an ESP-32 wireless pack for network connectivity. Each chapter has a list of recommended hardware and we have listed alternatives wherever possible. We leave it up to you to substitute components as you see fit.
If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book's GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
If you find any specific hardware-related issues with the code samples shared in the repository, please feel free to create a GitHub issue.
