Summary
In this chapter, we have learned a number of important things for Arduino. We learned how to declare functions, how we can play with functions, how to connect an SD card to an Arduino, how to read a file from the SD card using Arduino Uno, and how to create a new file on the SD card with Arduino. We have also developed code for handling files with Arduino. There are a number of exercises in this chapter. These exercises are for broadening your thoughts about Arduino. What you can do with a small piece on computer. I hope you learn all the techniques in this chapter in order to gain a better understanding of Arduino programming. If you have enough knowledge about file handling, then I welcome you to the next chapter of this book: Chapter 6, Arduino and C++.
