arduino pong clock sure 2416 and ds1307

danielb:
NOW WORKS !! ( and now I have understand the problem )

Hey that's great! Post a video on Youtube or something, it looks like it has a very nice case...

the only thing I must comment the code after the clock becouse the refresh was not every 1 second.
no problem becouse I don't want this code.

How long was it taking to refresh the Seconds?

You don't want the animated invader icon? Maybe you could leave it in if you commented the delay(500) instead of the invader stuff.
Try it!

Cheers!
