//

// 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)
