Updated Constructors to do all the pin() and interval() setups. All the setup can now be done in one step when instantiating the object. Added held() and retrigger(). See examples. Updated other examples to use the new constructor.

DESCRIPTION
|
|
====================
|
|
Example of the held() function for the Bounce 2 library
|
|
The held() function returns a 1 when the button has been held for a minimum of the hold interval or 500ms which is the default
|
|
|
|
An example of using this is in a menu where a user must hold a key down before he/she can edit something.
