Generally speaking, there are lots of options for wireless communication, such as infrared and laser, which have been talked about in **Part 2**.

* [**Chapter 4.1 - Infrared Controller**](/arduino-full-stack/04_infrared_sensors/005_infrared.md)
* [**Chapter 4.2 - Laser**](/arduino-full-stack/04_infrared_sensors/007_laseremitter.md)

In this chapter, some other widely used communication methods are to be discussed in detail, including:

* **Serial** port communication
* **Wifi** module - **ESP8266** and **Official Arduino Wifi Shield**
