Summary

In this chapter, we have learned about a lot of things, including control statements (if-else, loops, switch, and so on). All the control statements we learned are equally important for the next level of Arduino programming. This chapter might be a long one, but my suggestion is that you read the whole chapter without stopping. You should also do the exercises so that your learning remains in your brain for a long time. If you have any problems understanding any code or topic, then you will not be quite ready for the next chapter, where we will learn a lot of interesting things, including file handling and functions. If you are already familiar with all the topics of this chapter, you are most welcome to move onto the next Chapter 5, Functions and Files with Arduino.
