/***************************************************

  This is an example sketch for our optical Fingerprint sensor



  Designed specifically to work with the Adafruit BMP085 Breakout

  ----> http://www.adafruit.com/products/751



  These displays use TTL Serial to communicate, 2 pins are required to

  interface
