[@JiffiJiffJeff]

Every Arduino tutorial should be like this. So helpful!

[@PyroChimp75]

I just found these online and jumped straight onto YT to see if anyone had a tutorial up yet, thank you!!!

[@ediik]

same here

[@user-hc2of8xv4t]

hi, can you give the link code of the github back because it show 404 error

[@chamanavenkatesh]

this is the real point and very nice video

[@lashramtinilam9078]

Do you always need to connect to laptop whenever you are adding fingerprints ? Is there also an admin fingerprint

[@najihasufian4535]

is it normal if the capacitive fingerprint sensor gets heat up when i'm using ftdi? do i have to connect both 3.3v and p.s of capacitive fingerprint to vcc of ftdi?

[@jameskuria1664]

Can we add more fingerprints to the existing templates

[@a3macahis971]

do you have tutorial using Nodemcu wifi to used fingerprint of smart phone

[@manansai7840]

Hi!!! I am interested in this project. I just had a question. Can we use this sensor to unlock our pc as well??

[@ZJARDOON]

Very helpful! Thank you

Using this Fingerprint device with a NANO and the referenced sketch. Inconsistent results. The device works OK, but the sketch crashes a lot. I contacted dfRobot and they say (even though it's their sketch) that a hardware serial port must be used to avoid inconsistent results. I've tried obvious ways to do that (TX/RX pins), but it doesn't work. Do you have an answer to this? Thanks!

[@kiranjojare8451]

Can I do the same think with STM32F4?

[@lashramtinilam9078]

Can you also disconnect a circuit with this ?

What is the specification of this sensor ?

[@nocturnalduo1881]

What materials are you using?

Can you unlock a maglock with this ?

[@ellentao6559]

Hi, does anyone have the code since the link no longer shows it?

[@H0t.5tuff]

how to use this code with R503 finger print sensor?

[@GameMovieStudios2000]

can this work with windows hello or linux?

[@DirkB00]

Which FP sensor on the market can give the fastest result ? Not looking at price ... but need to connect to Arduino or ESP.... This one, I'm not really impressed with the speed looking at the video :)

[@user-qf5hk6py2i]

How can I connect it to an website Or a app

I want to do this and put it on my desktop pc, I am a little tech savy but I am still confused..

[@yasminbitar5378]

Hi, During my tests, I faced this message: teste:28:15: error: cannot declare variable 'fingerprint' to be of abstract type 'DFRobot_ID809' exit status 1 cannot declare variable 'fingerprint' to be of abstract type 'DFRobot_ID809' I copy and paste your code Could you help or suggest any solution? Thank you in advance

[@jovangarcia2935]

can you use two of this scanner in one arduino? scanner 1 for registration of fingerprint and scanner 2 for recognition of fingerprint that was registered in scanner 1?

[@fabianalfonsoflores1952]

Usually there is no need to use two. Instead, in the code you can handle permission for registrations and detections, but yes, you can connect as many sensors as Serial ports your hardware has

[@techhunter2005]

nice

[@seannolan7235]

is there a way to turn this into a lock, like have it only open to ID = 1 instead of other saved ID's

[@CETech4u]

Yes you can do that

[@kasek4164]

Could it be used to either not allow a computer to boot up (“cut” the power) until it’s read or be used as the “password” instead of typing in a password use it to unlock either windows or Mac?

[@anthonymercado3464]

Yes, something like this can be implemented through software or hardware. You can do a lot with arduino.. and also.. look into raspberry pi.

[@kasek4164]

@@anthonymercado3464 hmm might have to look into this then. I have a latte panda alpha so I could use the arduino on there no need for raspberry Pi. I just wouldn’t know where to begin never used arduino and not sure if I’d wanna buy all this to have it not work.....

[@camilotello3296]

What happened to the repository?

[@shreyasawant8908]

Sorry for asking such silly question. But how are sensor's those are on the back of our phones are so compact

[@arisoda]

Big money

[@CETech4u]

Its kinda the same sensor that I show in the video! This one is sleek and compact as well!

[@sekudha]

Pls make a tutorial on how to use this sensor for windows Hello Plss do it It would be very nice of u

[@bluestratos1901]

Could you pair this with a keypad lock as well? I'm trying to make something for my electronics class that stands out.

[@CETech4u]

Yes you can

[@protechnology550]

How connect gsm with this system

[@protechnology550]

Gsm with fp For alart

[@CodyL33OX]

The links to the code aren't here.

[@sameulrajkumar1852]

Can I use Arduino Uno r3 for this project

[@Pramod-Tayade-official]

That's what he is using

[@great871]

If we save fingerprints in array, if we turn off arduino, will they get deleted?

[@CETech4u]

Yes

[@dungpham-yy9om]

What's the output signal of one fingerprint?

[@CETech4u]

Bitmap image

[@dharmikprajapati4063]

Every time I connect a sensor with arduino nano, it says... Communication with device failed, please check connection. I am pretty sure connections are ok, I checked multiple times. Anyone can help me out ?

[@user-jx4fh1ij6u]

If you have solution please help us

[@itsSHKR]

plz

[@dharmikprajapati4063]

No. unfortunately I was not able to find solution either.

[@CreativeJE]

why are you putting so much force on the sensor ? and it feels really slow

[@thisfeatureisbad]

I would make a password manager for a PC from this fingerprint reader. It just needs some kind of really simple text (login and the password) encoding and decoding on an SD Card.

[@Acnaczc]

so 1 sensor outputting different text based on which finger you used yeah? did you manage to get that working?

[@thisfeatureisbad]

@@Acnaczc I don't have any fingerprint sensors right now. But, I'll try to make a simple authenticator once I get one in hands.

[@Acnaczc]

@@thisfeatureisbad alright. I am looking at making like a glove where each finger makes a different input that i might try set up for vr or something so im gonna be trying to look at this soon.

[@aiymankhan7222]

Can you add a second fingerprint with the existing code you provided?

[@CETech4u]

Yes

[@stoleneyesss]

Every time i connect a sensor with arduino nano, it says... Communication with device failed, please check connection My connections are 100% right as i have made the PCB of this circuit and have tested all connections multiple times. i have changed 4 sensors but getting the same result Please guide

[@dharmikprajapati4063]

same here. You find any solution ?

[@itsSHKR]

same any update?

[@mayank9266]

How to send finger print scanner data to mysql or any other database ? Plz help 🙏🙏

[@CETech4u]

You'll have to change the operation mode of the fingerprint scanner. I think the steps are mentioned in the user guide of the scanner.

Can this coding be used on the fingerprint type R503 ??

[@CETech4u]

Not tried

[@jaimenavarro9855]

Where save the ID?

[@CETech4u]

On the scanner.

[@arisoda]

@@CETech4u Why would they save in ON the scanner??? That's such a security issue. That's just stupid af

[@CETech4u]

Thats done to make the usage of the sensor easier for us makers. If you want you can bypass that and get the data off the sensor as well

[@arisoda]

@@CETech4u Do you think that would come at a significant time cost? Like a big delay?

[@suneelbhat4677]

Links are not working, people are asking for the same in youtube as well. are you guys are active or not??????

[@CETech4u]

Someone hacked our GitHub and reached out for ransom which we could not afford and hence we lost all our repos. It is now a very tedious task for us to build repos for more than 50 videos again. Hope this makes sense.
