Hi,
I am not really having problems with the unit. I would like to have some advice on a coding problem I have.
I want to build this item into a mobile unit. That provide some issues with enrollment as I dont want to add a keypad for a lack of pins available on my pro mini.
What I would like to do is to search through the library and find the first available id#. But alas it seems I cant find a way to make the Search function work.
Any ideas would be welcome.
Regards,
Fingerprint scanner find first available ID

I don't think you can do that.
Instead, I think what you want to do is to keep track of the next available ID in EEPROM on the Pro Mini. Initialize the value to 0, then update it in EEPROM every time you enroll a new fingerprint.
