Saving scores

I want to save score and send to my mobile

The best way right now is probably just to take a photo with your phone!

The other option, is to use something like the screen casting ability in some of the games provided by @crait in his repo…

And finally would be editing the actual code of games to output a high score through the serial terminal. This would require making changes which of course calls into question the validity of high scores in the first place.

If a game needs to validate high scores some kind of encryption key or hashing function could be used. But given the constraints of the system, this is more of obfuscation as it would be pretty easy to brute force whatever scheme we use on this platform.

thanks can we use wifi mount for this arduino

No wifi without adding extra chip, sorry!
