Buzzer class
To give a demonstration on how classes in c++/arduino work, i decided to code something easy and repeatable.
This class is meant to assign a input and and output source for a button to activate a buzzer, and a buzzer to be activated by a button.
This is done by using private variables and public functions that call to the private variables.
Inside of the class a constructor is made. (in c++ this is the name of the class itself.) every time the class is called uppon, the consctructor gets activated with the given data.
In this case the buzzer pin and Button pin are given with the new object.
This class uses public and private acces keys.
The variables to determine the pins are st to private so these can't be alterd by any other means besides the ones assigned to it.
