/* 4-Way Button:  Click, Double-Click, Press+Hold, and Press+Long-Hold Test Sketch

By Jeff Saltzman
Oct. 13, 2009

To keep a physical interface as simple as possible, this sketch demonstrates generating four output events from a single push-button.
1) Click:  rapid press and release
2) Double-Click:  two clicks in quick succession
3) Press and Hold:  holding the button down
4) Long Press and Hold:  holding the button for a long time

// Events to trigger

 void clickEvent()

 {
    ledVal1 = !ledVal1;
    digitalWrite(ledPin1, ledVal1);
}
void doubleClickEvent() {
    ledVal2 = !ledVal2;
    digitalWrite(ledPin2, ledVal2);
}
void holdEvent() {
    ledVal3 = !ledVal3;
    digitalWrite(ledPin3, ledVal3);
}
void longHoldEvent() {
    ledVal4 = !ledVal4;
    digitalWrite(ledPin4, ledVal4);
} 

только работает он с обыкновенной кнопкой а мне нужно с сенсором
