Overview of this book

With the release of the Raspberry Pi 2, a new series of the popular compact computer is available for you to build cheap, exciting projects and learn about programming. In this book, we explore Raspberry Pi 2’s hardware through a number of projects in a variety of programming languages. We will start by exploring the various hardware components in detail, which will provide a base for the programming projects and guide you through setting up the tools for Assembler, C/C++, and Python. We will then learn how to write multi-threaded applications and Raspberry Pi 2’s multi-core processor. Moving on, you’ll get hands on by expanding the storage options of the Raspberry Pi beyond the SD card and interacting with the graphics hardware. Furthermore, you will be introduced to the basics of sound programming while expanding upon your knowledge of Python to build a web server. Finally, you will learn to interact with the third-party microcontrollers. From writing your first Assembly Language application to programming graphics, this title guides you through the essentials.

Chapter 7. Exploring the Raspberry Pi's GPIO Pins

In this chapter we will explore the next piece of the Raspberry Pi's hardware, the GPIO pins.

GPIO stands for general purpose input/output. The pins can be used to connect external electronic devices to the Raspberry Pi. This also allows us to build our own circuits and control them using software we have written in languages such as C, Assembly, and Python.

In this chapter we will cover:

  • An introduction to the GPIO pins

  • Creating simple electronic devices that run off the pins

  • Writing Python applications that interact with the pins

We will start by walking through the GPIO pins and looking at what each type is.
