The script is patiently waiting for you to enroll a finger. Place your finger on the reader
and watch the output of the serial port and follow the instructions. A successful enroll-
ment looks like this:
Remove finger
Press same finger again
Remove finger
Press same finger yet again
Remove finger
Enrolling Successful
If there is a problem, and the enrollment process can be a bit finicky, you'll need to reset
the ATmega and re-attempt enrollment. In the same repository is a script,
reset.sh
,
that simply toggles the ATmega reset line. If you have troubles, reset your ATmega and
try again.
