Eggzact Science

  /* -------------- READ ME ---------------- */
  /* The goal of this script is to use the arduino
   *  as a web server, to publish the number of eggs. 
   * Maybe so it could send it as json
   *  

     Known issuses:
      - Hardware:
          - Switch / wiring / connection causes "boucing" signal
          intermitantly when button is pushed or wires bumped.
