Bloc 2. Projectes Pong

/*
* Pong
* 
* Play a simplified version of the classic arcade game, Pong!
* 
* In this game, a “pong” will move across five LEDs (VU-meter) 
* and bounce back and forth as players press the button. 
* Players must press the button at the right time in order to 
* return the pong.
