i have Finger Print Module Serial UART "CAMA-SM12"
and i can'nt turn on it on arduino mega
and i try this code and nothing happen
and this is the link of  finger print

/***************************************************
This is an example sketch for our optical Fingerprint sensor

Designed specifically to work with the Adafruit BMP085 Breakout
----> http://www.adafruit.com/products/751

These displays use TTL Serial to communicate, 2 pins are required to
interface
