In this chapter, you have learned how to recode and send infrared commands using the Arduino IR library with the raw data format. Further, you have learned how to activate the IR LED via the internet and send the IR command to the target device.

Throughout this book, you have learned how to integrate Arduino with shields, sensors, and actuators that can be controlled and sensed through the Internet. Further, you gained knowledge about Arduino cloud computing with platforms and technologies such as Temboo, Twilio, and NearBus.

You can adopt, fully or partially, the projects that were discussed in this book for your Arduino IoT projects, and also, you can hack them for further improvements or alternations. In addition, the project blueprints can be used for your hobby, school, or university projects, as well as for home automation and industry automation projects.
