 This file includes the main Arduino sketch that can be **edited and uploaded to the device**. The sketch includes the `thingProperties.h` file, the `setup()` and `loop()` functions, and an empty function for every **Read & Write** variable. The code below is a basic example of an auto generated code in the sketch file, using the same variables from the previous example displayed in `thingProperties.h` section.

 The full editor allows for more control over the code and its libraries and provides access to all files included in the sketch, as well as more editing and sharing options.
