-Since the functions are scoped under a specific name called "nicla", you can use the following statement to have convenient access without repeating explicitly the namespace before every function call.

+Since the functions are scoped under a specific Class name called "nicla", you need to explicitly write it before each statement.
 
 The LEDs need to be started along with the Nicla inside `void setup()`:

 ## Sensors
 
 There are three ways to read from the on-board sensors:
