MIT App Inventor Projects (1 ed)

This book is about developing apps for Android-compatible mobile devices using the MIT App Inventor online development environment. MIT App Inventor projects can be either standalone or use an external processor. In standalone mode, the developed application runs only on the mobile device. In external processor-based applications, the mobile device communicates with an external microcontroller-based processor, such as Raspberry Pi, Arduino, ESP8266, ESP32, etc. This book presents numerous tested and fully functional projects, both in standalone mode and using an external processor. Full design steps, block programs, circuit diagrams, QR codes, and full program listings are given for all projects. The projects developed in this book Are unique in that it is currently the only one that teaches how to develop projects using Wi-Fi and Node-RED with MIT App Inventor. The book is aimed at students, hobbyists, and anyone interested in developing apps for mobile devices. All projects presented in this book have been developed using the MIT App Inventor visual programming language. There is no need to write any text-based programs. All projects are compatible with Android-based mobile devices. Full program listings for all projects and detailed program descriptions are given in the book. Users should be able to use the projects as they are presented, modifying them to suit their own needs.
