In this first, advanced chapter, we learned a bit more about how to deal with new concrete concepts such as storing data on non-volatile memories (internal and external EEPROM), use GPS module receivers, draw on graphical LCD, and use a nice Arduino Shield named Gameduino to add new features and power to our Arduino. This allowed it to display a VGA signal and also to produce audio. We also learned the use of Arduino as a very portable and mobile device, autonomous from the power supply point of view.
In the next chapter, we are going to talk about networking concepts. Creating and using networks are usual ways of communication today. We will describe wired and wireless network use with our Arduino projects in the next chapter.
