SerialMonitor by BREVIG http://alexanderbrevig.com
A simple password application that uses the serial monitor as input source.

    #include <Password.h>

    Password password = Password( "1234" );

    byte currentLength = 0;

    void setup()
    {
      Serial.begin(9600);
      Serial.println("Try to guess the password!");
      Serial.println("Reset with ! evaluate with ?");
      Serial.print("Enter password: ");
    }

    void loop()
    {
      if (Serial.available())
      {
        char input = Serial.read();
        switch (input)
        {
          case '!': //reset password
            password.reset();
            currentLength = 0;
            Serial.println("\tPassword is reset!");
          break;
          case '?': //evaluate password
            if (password.evaluate()){
              Serial.println("\tYou guessed the correct password!");
            }else{
              Serial.println("\tYou did not guess the correct password!");
            }
          break;
          default: //append any keypress that is not a '!' nor a '?' to the currently guessed password.
            password << input;
            currentLength++;

            //Print some feedback.
            Serial.print("Enter password: ");
            for (byte i=0; i<currentLength; i++)
            {
              Serial.print('*');
            }
            Serial.println();
         }
      }
    }
