What you need for this book
There are no special demands for implementing the projects of this book on the Raspberry Pi, except the essential hardware components! You can use a personal computer with Linux, Windows, or Mac OS X to connect the Raspberry Pi to it. Any of the Raspberry Pi models available in the market (Raspberry Pi 1 models A+, B, or B+, or Raspberry Pi 2 model B) should be okay for performing experiments on the code. You can refer to the Appendix, Shopping List, for the requirement of hardware before getting into Chapter 3, Measuring Distance Using Ultrasonic Sensors, and the later chapters.
