Problema scrittura/lettura EEPROM!!

Salve a tutti, ecco il mio problema: quando arduino si avvia, vorrei che andasse a cercare il contenuto di due file, dove sono salvate una password e una chiave. Queste le voglio salvare nella EEPROM, supponendo che sia una soluzione più "sicura" rispe...

Si, ma senza illuminazione il sensore non funziona perché calcola la il colore della superficie da testare in base alla riflessione della luce del led.
Se guardi il codice, il sensore esegue una letture ogni 10ms prima del rosso poi del verde e infine ...

Woman Hacks Legend of Zelda for Gender Bending Role Reversal

Posted: 26 Mar 2013 02:00 AM PDT

A woman named Kenna W. has hacked the Legend of Zelda so that (the female character) Zelda can save (the male character) Link:

This is one of those things that seems so obvious, it feels like someone should have done it before. After all, just last week someone finally got the idea to mod a Donkey Kong ROM so that Pauline could save Mario.

That's exactly what inspired Kenna W., a professional animator, to mod a Legend of Zelda ROM to allow you to play as, well, Zelda. "For me, I played my first Zelda game when I was pretty young, and at the time, I thought the game did star Princess Zelda," Kenna writes. "I figured I'd get to play as a magical battle princess that saved her kingdom. The game was fun, but I was bummed out that I never got to play as Zelda." Likewise, 26 years ago, I thought it strange that the game was named for a Zelda but featured no playable character by that name.

Re: SoftwareSerial problems

You have 4 hardware serial ports on the Mega. Why do you need 4 software serial instances, too?

You are aware, are you not, that only one SoftwareSerial instance can be listening at once? You are aware, are you not, that you must actively make an insta...
