Going Wireless

In this chapter, we are going to cover wireless communication between the computer and the Arduino. There will be some occasions where we will want to physically detach ourselves from the Arduino, where a wireless connection can be useful. This can be the case when building an interface for a performer that doesn’t want to have cables hanging out of them. To have wireless communication, we will need some extra hardware. There are various options, depending on the actual interface we want to build. Here, we will cover the scenarios, the XBee radios, and WiFi.
