Biometric Sensor in Motorcycle Hornet

/*************************************************** 
  This is an example sketch for our optical Fingerprint sensor

  Designed specifically to work with the Adafruit BMP085 Breakout

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