Debouncing a button
May 4th, 2009, 8:40am  
created a simple button class and I am trying to add debouncing can anyone make any suggestions?

I look for button presses with:
if(myButton.buttonPressed())

Thanks.

Code:


class button { 

//button locations
  int buttonLocX; 
  int buttonLocY;

//buton sizes
  int buttonWidth;
  int buttonHeight;


  button(int x, int y, int x1, int y1){
    buttonLocX = x;
    buttonLocY = y;
    int buttonWidth = x1;
    int buttonHeight = y1;
  }
  
  boolean buttonRoll(){   //look for mouse over button
    if (mouseX>buttonLocX-5 && mouseX<buttonLocX+x1 &&  mouseY>buttonLocY-5 && mouseY<buttonLocY+y1){
    return true;
  }
    else{
   return false; 
}
  }
  
boolean buttonPressed(){
if (this.buttonRoll() && mousePressed){
      return true;
} else {
  return false;
}
}

}

You will probably want to detect when the mouse was pressed and store it in another boolean.

Basic idea:
buttonClicked = mouseWasPressed && !mouseIsPressedNow;

What NoahBuddy said. If you need more help, see the Arduino  debounce tutorial:
