Basic Pi GPIO example

In this demno of the Python Arcade library, I demonstrate moving backgrounds, sprites, sound effects (now working with zero lag!), and scoring.
import random
import arcade
import _thread
class Fireball(arcade.Sprite):
def update(self):
move_rate = 10
self.center_y += move_rate

In this simple demo we bounce a sprite over a moving background to show the basic functions of the Python Arcade module
