In this chapter, you took a look at the different parts of the Raspberry Pi board and learned a bit about how it came to be. You also learned about the importance of a good power supply and how a powered USB hub can help alleviate some of the power drain caused by hungry USB peripherals.

We then gave the Pi an operating system to run by downloading NOOBS to help us install Raspbian onto our SD card. Raspbian was booted and configured with the raspi-config utility. You also learned a few helpful Linux commands and how to set up remote connections from SSH clients over the network.

Finally, you learned how to keep Raspbian up to date and how to create a complete backup image of your precious SD card.

In the upcoming chapter, we'll be connecting sound gadgets to the Pi and getting our feet wet in the big pond of spy techniques.
