GT511C1R Fingerprint Scanner with Arduino UNO

Hey all,

I connected my fps with an arduino uno and it worked without issues. Here is my question; can I check how many seconds the user presses their finger on the fps? I want to make the enrollment and identification in the same script and for example, if you press for 5 seconds it starts enrolling. If not possible maybe tap count? Any help would be appreciated.

Sure - you would start a timer on pressing, and once it exceeds your given threshold (5 sec), run the block of code for enrollment :smiley:
