Good morning, first of all sorry for my long message and for my English.
I would like your help in choosing the right products. I do not know from electronics but I hope with your help I can make what I want.
I am building an office and I want to integrate on its surface a fingerprint reader with which I can enter windows when I open the pc or unlock folders that I have inside the pc.
I saw that many use the Arduino.
I would like to make a construction that does not have to interfere with the computer motherboard with cables and so on. I would rather connect it simply to a USB which from what I understand is done with the Arduino UNO which has a USB port.
If supports it, I want to put a fingerprint like this
To "pin" a fingerprint reader on the Arduino, to connect the Arduino to the computer with a USB cable and then to install on the PC what is needed so that I can unlock the windows with a fingerprint
Is it easy to tell me what I will need to procure to make what I told you above?
Sorry if I stunned you and I hope you can help me.
Have you the datasheet for that fingerprint reader?
How - with the keyboard or mouse - do you normally perform the "unlock" function on the computer for each of the operations to which you refer? Does the procedure itself depend on which operation it is, in which case how would the Arduino know which one to perform?
Thank you for your answer. My problem is not just the right choice of mustard. Let's say I choose Leonardo. Can I put the fingerprint reader I put above on Leonardo? And then how do I make the code? I do not know...
Following that video tutorial will make this a harder project than needed.
As mentioned above a Pro-Micro is the best fit here (and bypasses a bunch of steps in that video)
Your first step/question is, enrollment. (adding fingerprints to your 'library/database')
You can do this using Windows or you can do this using the Arduino.
After you have your finger print(s) added, you can then write the sketch/code (should be easy enough to edit one of the Adafruit library examples...no?) that will 'check' any finger laid upon the sensor, and compare it to your collection of fingerprints you have added.
If a match is found.. it is very easy to have the Pro-Micro act as a HID (human input device...aka: keyboard) to send 'commands/actions' to the connected PC.

"However, in order for it to work, it is necessary to replace the finger.fingerFastSearch() command with finger.fingerSearch() or the learner recognizes the sensor but does not find the finger. "
