Fingerprint Sensor With Arduino UNO

Using Arduino Project Guidance
1

Hello,
This is my first arduino project. Basically what I need to do is to connect this fingerprint scanner:

using this cable:

to my arduino UNO board and gain access to the scanner by using it with the Windows program shown on page 33 of this pdf:

There is not much information on the internet about how to use this fingerprint scanner. I'm not even sure how to properly connect it to the arduino itself. Any help would be much appreciated. This project is for an independent study for my undergraduate degree in computer science.
Thank you.

The link you gave has (in the user comments) and example Arduino Sketch:

That sketch I believe is only for an Arduino Mega. I tried compiling the code, and i get the error that Serial1 was not declared in the scope. I found out that serial1 only works with the Mega.
What i really need is a way to use the arduino UNO as a FTDI breakout board as shown in this picture:

The scanner seems to use 9600 baud serial so you could connect to it using software serial on the UNO and then pass data between software serial and Serial. Look at the software serial example included with the library.

I do not know how else to put this to you.
Did you bother to read more than marketing glossies about the scanner? ( first link you posted)
There is a sample code attached to the first link.
Cheers

Hello guys I am new in this project, I bought a fingeprint sensor, but I have the arduino leonardo board, I was checking the fingerprint project but this don't work for me I don't know if this project can't work with arduino leonardo? someone have a idea about it?

Regards.

How about making your own thread, instead of Hijacking one?

On the Leonardo connect to pins 0 and 1 and use Serial1

Serial on the Leonardo is handled internally because the chip has on board USB, So the hardware serial is mapped to Serial1
