Congratulations! You've completed the first stage of your journey. You have your Raspberry Pi, either a 3 or a Zero, up and working. You have 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 to do something. In the next chapter, you will be introduced to resources ranging including open source software and inexpensive hardware, and start to build your robotics projects. For the first project, you'll be building your very own R2D2.
