Hello, i just bought this fingerprint Module ( Interfacing AS608 Optical Fingerprint Sensor Module with Arduino). I'm using arduino uno and library from adafruit fingerprint and uploaded the example enroll sketch. But my problem is my fingerprint module doesn't detected in program (Did not find fingerprint sensor).
i use this topic ;Cut Male-to-male connector into half and Connect those cut ends with the sensor wires, and the male connection to arduino
but my problem doesn't solved yet ?
Diagram :
i use Adfruit library v2.0.4
The code i use :
/*
AS608-Optical-Fingerprint-Sensor-enroll
Home
based on Adafruit Library
*/
