Now that we are at the end of the book, take some time to go over the projects that you have successfully built. We have completed some projects, ranging from the beginner level to the advanced level, and learned a lot about the intricacies of working with the Raspberry Pi and all its parallel concepts firsthand. Starting from the introduction of the...
