Chipkit Magic-8 Ball

by shedboy71

In this example we will create a Magic 8-ball using an Chipkit Uno and an LCD keypad shield, when one of the buttons is pressed a random message will be displayed.

The Magic 8 Ball is a toy used for fortune-telling or seeking advice, developed in the 1950s and manufactured by Mattel. It is often used in fiction, often for humor related to its giving very accurate, very inaccurate, or otherwise statistically improbable answers.

  {
    lcd.clear();
    output = phrases[random(numberofphrases)]; //Chooses phrase
    lcd.print(output);
  }
