I am having issues with activating adafruit fingerprint sensor
Rugged Panel Mount Fingerprint Sensor with Bi-Color LED Ring (R503) [/b]
Wired as instructed
arduino Uno & R503 fingerprint sensor by adafruit
The sensor doesn't blinks at all at any time
After uploading the adafruit enroll get a message
adafruit did not find fingerprint sensor :(
soldered sensor wires to thicker male pins wires to insert to a board and tested for continuity - rings ok - and the
micro controller is ok as well tried to power cycle by disconnecting / reconnecting the 3v and the arduino as well
what else should I try? or the sensor is defective?
Thank you everybody!
