Summary
In this chapter, we have learned a lot of things. We learned the characteristics of OOPs and we learned how to configure a GSM Shield with the Arduino board. This chapter is one of the most important chapters if you want to improve your use of the microcontroller and OOPs concepts. I do not recommend that you skip this chapter. If you feel this chapter is hard, try to study and do the exercises in a silent environment and do the electrical parts with caution. You might get a number of errors. Don't feel disappointed; just move to Chapter 10, Few Error Handlings. I hope this chapter won't be that hard for you. You will find a number of solutions to the problems you might find while working with the GSM Shield and Arduino. In the next chapter, we will learn two interesting thing-pointers and structure of C programming.
