The initial chapters will provide detailed steps for building the example prototypes. However, sometimes during the course of the chapters, the reader will be subtly encouraged to become more independent. As you proceed through the chapters you will notice that the book starts covering only the bare minimum details, while you start understanding and doing more on your own.

• If you are a beginner, go through the chapters one by one, in the order laid out in the book.
• If you have a basic knowledge of Arduino prototyping then you may start from Chapter 4, Day 2 - Interfacing with Sensors.
• If you are already aware of prototyping with Arduino, then you may start from Chapter 6, Day 4 - Building a Standalone Device,from Day 5 onwards.
• Chapters up to Day 6 are for general device prototyping, whereas starting from Day 7 onwards the chapters deal with wireless communications. You may choose as per your requirements.

If the learning curve is perceived to be steep, then you are advised to pause, relax, and revisit the chapters as many times as needed. However, it is recommended that at no stage of the book should you rush; imbibe steadily and let the concepts sink into you so that you can understand and feel how Arduino-based prototyping is done.
