Hello All-
I am working on a project that involves a fingerprint scanner and I am using this: Fingerprint Scanner - TTL (GT-521F52) - SEN-14585 - SparkFun Electronics.
I am using this sketch from github: GitHub - sparkfun/Fingerprint_Scanner-TTL: Repository with example code for SEN-14585 & SEN-14585 at SparkFun.com
I am using an Arduino Uno and Arduino IDE 1.6.7
When I set up the circuit and upload the code, everything works fine. In the serial monitor it reads
"Press finger to Enroll #2"
However when I place my finger on the scanner, either nothing happens or it reads "Failed to Capture Finger."
The FPS has worked on two occasions and that is all, so I have seen it work properly.
I have scanned several of the forums for posts regarding this FPS and no one seems to have had this issue.
If anyone has any suggestions I would greatly appreciate it.
Thank You,
John

Is this an issue with the fingerprint scanner?
