//
//  Summary:  IS_Button is a class which implements the SmartThings "Contact Sensor" device capability.
//			  It inherits from the st::InterruptSensor class.
//
//			  Create an instance of this class in your sketch's global variable section
//			  For Example:  st::IS_Button sensor(F("button1"), PIN_BUTTON1, 1000, LOW, true, 500);
//
//			  st::IS_Button() constructor requires the following arguments
//				- String &name - REQUIRED - the name of the object - should be "button1", "button2", "button3", etc...
//				- byte pin - REQUIRED - the Arduino Pin to be used as a digital input
//				- long reqNumMillisHeld - Required - number of milliseconds required needed to detect a "Held" condition versus a "Pushed" (default = 1000)
//				- bool iState - OPTIONAL - LOW or HIGH - determines which value indicates the interrupt is true (default = HIGH)
//				- bool internalPullup - OPTIONAL - true == INTERNAL_PULLUP (default - true)
//				- long numReqCounts - OPTIONAL - number of counts before changing state of input (prevent false triggers) (default = 500)
//
//  Change History:
//
//    Date        Who            What
//    ----        ---            ----
//    2017-03-25  Dan            Original Creation
//    2019-09-7   Dan Ogorchock  Send Button 'init' messages for automatic setting of numberOfButtons attribute
//    2020-09-19  Dan Ogorchock  Modified to not wait until button is released to send 'held' event, also added released events
