Arduino_based_Ping_Pong_game

Remember I wrote this code way back and it is not programmed beautifully and has huge scope of optimisation ... my Apologies !
This game uses an 8X8 DotMatrix for Display
Two Potentiometers for Wedge control
Arduino as microcontroller
It is ping pong game
Which uses two wedges to hit the ball on each side
Game is for two players
And if one is hitting a ball with moving wedge then ball also changes direction corresponding to wedge movements
User can configure the speed of ball
