bool isPressed();            //returns true if button is pressed

bool isReleased();           //returns true if button is released
bool isHeld();               //returns true if button is pressed in timeout
bool isHold();               //returns true if button is pressed after timeout

bool hasSingle();            //returns true if button is clicked once
bool hasDouble();            //returns true if button is clicked twice
bool hasTriple();            //returns true if button is clicked three times

uint8_t hasClicks();         //returns clicks after stopping clicking
uint8_t hasClicksNow();      //returns clicks
uint8_t hasClicksWithHeld(); //returns clicks before pressing
uint8_t hasClicksWithHold(); //returns clicks before holding

uint16_t holdInMillis();     //returns holding time after released
uint16_t holdingTime();      //returns pressing time

Using example

EMFButton btn (3, 0);

void setup() {

}

void loop() {

  if (btn.isClicked())

  if (btn.isReleased())

  if (btn.isHeld())

  if (btn.hasClicks())
