Previous chapters introduced the Raspberry Pi hardware, and you learned how to use Python to program it. You installed the operating system, configured it for your use, and set up remote access so that you can program the Pi without connecting a keyboard, mouse, and monitor directly to it. You learned the basic structure of a Python program, syntax, and enough about the language to start writing programs.

Next, you are going to learn how to use the Raspberry Pi’s GPIO interface to interact with the physical world. This is crucial for robotics because it’s how ...
