 The [Arduino IoT Cloud](https://create.arduino.cc/iot/) has support for events and callbacks. This can be used to trigger specific functionalities depending on what state your device is in. 
 
-You can for example trigger a specific block of code whenever the board is in a **connecting**, **synchronized** or **disconnected** state. In this brief document, we will explore how to set it up, using an example from the [ArduinoIoTCloud](https://github.com/arduino-libraries/ArduinoIoTCloud/blob/master/examples/ArduinoIoTCloud-Callbacks/ArduinoIoTCloud-Callbacks.ino) library.
