test post with code

I can’t embed github code 🙁

int size = 0;
int increment = 3;
void setup() {
size(400, 400);
}
void draw() {
background(255);
noFill();
strokeWeight(20);
ellipse(width/2,height/2, size, size);
size = size + increment;
if ( size > 300){
increment = -increment;
}if((size<150) && (increment<0)){
increment = -increment;
}
}
