Ondas Esféricas que se desvanecen en Loop

I really apreciate last answers. Now I need to repeat indefinitely the second circle of my code, the one that is moving, once every second. Thank you so much. float x=0; float y=255; void setup(){ size(270,540); background(0,0,0); noStroke(); } void draw (){ background(0,0,0); strokeWeight(3); stroke(255,255,255); noFill(); circle(width/2, height/2, height/10); stroke(255,255,255,y); circle(width/2, height/2, height/10+x); x=x+1; y=y-1; }
