I'm taking the code found from the github site, under adafruit/Adafruit-Fingerprint-Sensor-Library. I changed the file type from a .cpp to .ino to get the arduino software to open the file. Then when I try to download it to the uno I get the below message.
C:\Users\Clayton\Downloads\Adafruit-Fingerprint-Sensor-Library-master\Adafruit-Fingerprint-Sensor-Library-master\Adafruit_Fingerprint\Adafruit_Fingerprint.ino:17:34: fatal error: Adafruit_Fingerprint.h: No such file or directory
