cdupaty 5:022e24a51359 2 This is an example sketch for our optical Fingerprint sensor
cdupaty 5:022e24a51359 3 Designed specifically to work with the Adafruit BMP085 Breakout
cdupaty 5:022e24a51359 4 ----> http://www.adafruit.com/products/751
cdupaty 5:022e24a51359 5 These displays use TTL Serial to communicate, 2 pins are required to
cdupaty 5:022e24a51359 6 interface
cdupaty 5:022e24a51359 7 Adafruit invests time and resources providing this open source code,
cdupaty 5:022e24a51359 8 please support Adafruit and open-source hardware by purchasing
