Congratulations! You've completed the first stage of your journey. You have your Raspberry Pi Zero up and working. No gathering dust in the bin for this piece of hardware. It is now ready to start connecting to all sorts of interesting devices, in all sorts of interesting ways. You have, by now, installed a Raspbian operating system, learned how to connect all the appropriate peripherals, and even mastered how to access the system remotely so that the only connections you need are a power supply cable and a LAN cable.

Now, you are ready to start commanding your Raspberry Pi Zero to do something. The next chapter will introduce you to the Linux operating system and the Emacs text editor. It will also show you some basic programming concepts in both the Python and C/C++ programming languages. Then, you'll be ready to add open source software to inexpensive hardware and start building your robotics projects.
