HELP ME....!!!!

(I've checked fingerprint enrollment in the arduino example code...In that code the sensor works fine... it blinks continuously for scanning...But in this code the sensor is not blinking as it should be....)
go to File -> Examples -> scroll down to Adafruit Fingerprint Sensor library -> enroll. change the tx and rx pins to whatever you have and then run. open serial monitor and there you have it!
