R503 Interface with Arduino

Hello Guyzz,

I am making Attendance System using R503 and Arduino UNO.
I followed the below site Instruction to enroll new finger but Arduino is not detecting sensor.

site:

The Adafruit tutorial says:

If you get "Did not find fingerprint sensor :( " check your wiring, maybe swap the RX and TX wire as that's a common issue

You can see this old thread too: Fingerprint Sensor (R503) not working - #3 by Arrow008
