Arduino Ping pong with 8*8 Dot matrix & Max7219

There are lots of Arduino ping pong tutorial over the internet. But most of them are for two players .As have no one to play with me so i was find a tutorial which is for single player .Luckily i have found one but that is not that clear and didn’t contain so much information .So i decided to write a tutorial so that u guys who are single like me can build a ping pong and pass your time.”
