Exploring Arduino uses the popular Arduino Microcontroller platform as an instrument to teach budding hobbyists and engineers (at every stage) about topics in electrical engineering, programming, and human-computer interaction. Arduino expert Jeremy Blum walks the reader through increasingly advanced exercises in using the Arduino to accomplish useful, artistic, and educational tasks. In addition to walking the reader through specific projects, the book will aim to introduce best practices in programming and design that the reader will be able to apply to their own projects. Code snippets and schematics will serve as a useful reference for future projects even after the reader has mastered all the topics in the book. The book will include a number of projects that utilize different capabilities of the Arduino, while interfacing with external hardware.
