For this assignment we are using a rasberry pi with breadboards attached and an 8x8 LED matrix controlled by a joystick. We must figure out how to make a pong game on the LED matrix. When run, there is a paddle on the bottom of the matrix length of 3 dots, and a ball lenght of 1 dot will drop from the top and you must hit the ball with the paddle and the ball will go up then back down and repeat until you miss the ball then game over. Need help finishing the code below to get the paddle and ball created can anyone help?
