Fingerprint Scanner - 5V TTL (GT-511C1R)

Development Boards Arduino

Hello

I am new to Arduino. I must have made a project with an Arduino Uno board and Fingerprint Scanner - 5V TTL (GT-511C1R).

The purpose of the project is that I must be able to lie my finger on the scanner, and turn on the computer

I find it hard to find some libraries and examples.

Can anyone help me?

On Sparkfun’s product page for the GT-511C1R, retired product,

There’s a link to a github Arduino project to talk to the scanner using simple logic voltage level UART interface.

The github

https://github.com/sparkfun/Fingerprint_Scanner-TTL

project, at a glance, has common C code and it’s a rather small amount of code.

So you might be able to get this running with an Arduino board then move it if need be.

Discontinued product so you may have a hard time finding a 2nd one as a repair-spare.
