Password protected Secret Telling Arduino!

I was fooling around with my Arduino UNO and started making some cool things. One of them was a password protected secret telling Arduino! You don't need anything but a computer and an Arduino!

Step 1 Programming

This is the code I used!
void setup() {
pinMode(13, OUTPUT);
  Serial.begin(9600);
  Serial.println("HELLO WORLD!!!!!!!!!!!!!!!!!");
  delay(1000);
  Serial.println("I am Arduino!");
  delay(1000);
    Serial.println("Input the correct passcode and I will tell you the secret!");
}

void loop()  {
  start:
const char passcode = 'lolification';

    if (Serial.read() == passcode) {
        Serial.println("I want Pizza"); //input secret line one here here
        delay(1000);
        Serial.println("I am Cold");//just copy paste these with the delays to keep on adding lines
                delay(1000);
        Serial.println("He broke an office computer!"); 
        delay(1000);
        Serial.println("I like when people program me!!!!!"); 
        delay(1000);
        goto start;
    }
  }

Like if you using RFID's for a door, you could store your RFIDs information, copy it to another card. Delete that card out of the memory?

Theoretically, yes but it wouldn't be the way you are thinking of it. It would be more like, the other card would still have the same ID, but when read its processed the same as a valid card. Thanks :D

like... how would you program it to save, copy , and delete...

[simonfrfr]

What do you mean by save copy and delete (like what)?

[zer0nerz]

stored information.

Wow thats pretty damn cool. Im new to C++ or C, i never understood where does all this code pop up from? Like how do you know that the Arduino will respond properly to what you tell it to do? like the pins and the analog stuff. Is there something i can get. Or is it more simple than i think? My C++ is basic... i can't write anything. But I understand some things. Just not enough.

Ok this is very simple, First all you do is basically learn from the examples, then you make your own codes. Examples can be learned from by copying the code (not copy paste). Really to tell the truth, I need to test the code several times until I get it to work properly. An example of a code that is doesn't work the way it should is, http://www.instructables.com/id/Sentriduino-Its-the-all-new-Sentry-turret-made-of/ in algorithm 1. I stopped trying to make that code work right because sometimes it is better to redo the whole thing. Thanks :D

this is cool :D made by yourzelf?

[simonfrfr]

yes, I made it one day when I was bored in my Mom's office
