In this chapter, you have gained a lot, and built your first Arduino Internet of Things (IoT) project, an internet controlled power switch, which is very smart. Using your creative knowledge, you can take this project to a more advanced level by adding many more functionalities, such as an LCD screen to the switch to display the current status and received user requests, or a feedback LED to show different statuses, and so on.
In the next chapter, you will learn how to build a Wi-Fi signal strength notification system using Arduino wearable and Internet of Things. Use the basic knowledge about Arduino IoT gained from this chapter to build the next project more successfully. Always be creative!
