Welcome to my book. I wrote this book! Yes, me! My name is Lorraine, and I love coding. I think coding is the portal to everythingthe portal to having fun, being creative, being serious, and yes, saving the world. Superheroes of the future will not have superpowers or a cape; theyll have a laptop and great Wi-Fi.

I am so grateful to be given the opportunity to write this book by McGraw-Hill, and I would particularly like to thank Elizabeth Houde for all her help and guidance, and Patty Wallenburg for her amazing editing.

Im very lucky to live near a wonderful small school that my sons attend. The models in this book are all from my sons school and are (and will be!) in the Code Club, which I run every week. Thanks to Indie, Olive, Rose, Ffion, Catherine, Jasper, and Bailey for patiently posing for my photos and for their endless smiles and giggles.

Thanks to my reviewers: Michael, Rachel, Hannah, Lynne, Phil, James, Carolyn, Liam, Angie, and Nicole.

Thanks to my sons, David and SamDavid for being a model in this book, testing out the code in the missions, and being more excited about this book than me and Sam for also being a model in this book, doing his best to help out, and constantly asking me when the book was ready.

Thanks to my Twitter friends, Laurence, Darren, and Paul, for their endless enthusiasm and inspiration. To Helen Leigh, for blazing the trail with her book The Crafty Kids Guide to DIY Electronics: 20 Fun Projects for Makers, Crafters, and Everyone in Between (McGraw-Hill Education TAB, 2018). To my lifelong friend Katie for keeping me going over long distance and my number two fan Rachel, who always knows just what to say.

With this book, you can code missions to help save the world using the BBC micro:bit, the Circuit Playground Express, and/or the Raspberry Pi. At the end of this Introduction, you will find a list of missions by device, difficulty, and whether you need extra equipment.

NOTE TO PARENTS/GUARDIANS

The Raspberry Pi is more suitable for older children or those with a lot of help from an adult, especially when setting it up. Many children will not have experienced Linux before, and the environment will not be familiar to them. The MakeCode platform for the BBC micro:bit and Circuit Playground Express is really easy to use. It is very similar to Scratch, which many children will have used before.
