</div>

float brush\_x = 10;  
float brush\_y = 10;

void setup() {  
size(800,800);  
background(0);  
rectMode(CENTER);  
frameRate(300);  
}

void draw() {  
if(mousePressed == true) {  
noStroke();  
ellipse(mouseX,mouseY,brush\_x,brush\_y);  
}  
if(keyCode == DOWN) {  
brush\_x = brush\_x - 1;  
brush\_y = brush\_y - 1;  
} else  
if(keyCode == UP) {  
brush\_x = brush\_x + 1;  
brush\_y = brush\_y + 1;  
}

}

This is my code and whenever I press the up/down arrow it adds 1 to the size every frame even if I release it it still keeps going. Does anyone know how to fix this?

The `keyCode` variable holds the most recently pressed key, whether that key is still pressed or not. You might want to also check the `keyPressed` variable as well:

```auto
if(keyPressed){
 if(keyCode == DOWN) {
  brush_x = brush_x - 1;
  brush_y = brush_y - 1;
 } else
 else if(keyCode == UP) {
  brush_x = brush_x + 1;
  brush_y = brush_y + 1;
 }
}

```
