Getting Started with the Fingerprint Sensor

[@ncalarms6022]

This is amazing. I am a huge fan of the work and ingenuity that goes into the adafruit products. I have used the RGB negative LCD and the LCD display shield in my fire alarm control panel that I made with my arduino UNO ,your shield and LCD, some relays, and batteries. all I need is to learn how to use EEPROMS with Arduino and then I'll be set. thank you for doing what you do to make our projects possible.

[@ShariqAyazTech]

+Gpexalarm101 hi,
can you please guide me the same product can store fingerprint image in external storage? or computer. or is there any way to send it to my application?

[@audigex]

Quite expensive for what it is - but I can see uses for it: locking doors for some children (ie not allowing them into the kitchen) without requiring keys all the time, for example. I'm thinking of incorporating one into a home-theatre system, to enforce age-restriction of programmes.

[@vino1415]

best video please never stop to any video in you tube, it will help more than billion people
thanks a lot it help me a lot

[@legaspi19]

how are we going to make fingerprint data to be accessed for user maintenance such as (add,delete,etc)? thanks!

[@premraval-pr]

Hello, Adafruit.........I am stuck. I have attached all the wires as shown in the video even when I upload it to board the fingerprint sensor lights up......but when I am using the ENROLL example then it is always giving the same error in the output. i.e. "Adafruit Fingerprint sensor enrollment
Did not find fingerprint sensor :(
"
I don't know why. Please help me with this

[@adafruit]

All our videos are available for HD download on Vimeo. Soon UA-cam will have this function too.

[@FrancXPT]

youtube still didnt add it hhh lol

[@ecarvalho17]

It has, but only for Premium members and you have to watch the video through UA-cam despite being downloaded

[@Jorvanius]

Hi, I've been learning about this and want to ask if is there a way to storage fingerprint in another space besides the one that the sensor bring (to have more fingerprints)?

[@ItsVannah]

could you make a video on how to use this with the solonoid to lock a safe? it would be awesome sauce if you did!

[@sikz26300]

Hmmm, so the sensor stores the finger print data.... is there a way to export this? I'm thinking of having multiple modules reading from the same db of stored fingerprints

[@seyedmarashi]

very good and simple!!!! thanks

[@cicilytg1473]

what do you mean 'connect power and ground', how do i do this? do i need extra wires? if so do they need to be specific wires? are they jumper wires ?

[@shakirullah4936]

will be thankful for you satisfctry answer.. waiting

[@emanuelecoppola]

120/5000
Congratulations for the guide.
I wanted to ask is it possible to take the imprint of the whole finger and not just the central part?

[@_a_x_s_]

Suddenly appeared in my recommendations, check this finger sensor from 9 years ago out lol
I am wondering whether there is any improved version of this sensor recently?

[@madhukeshnp]

nice tutorial. please make a video on fingerprint sensor and rfid combined lock. that would be awsome. please it's a request. thank you in advance

[@poptropica121]

Good Job!

[@yogeshlulla2328]

Can you please help that how can I access and extract data of this fingerprint print sensor as I need them to be uploaded on cloud.

[@metrocityproductions7152]

Can you do this on a lock for a locker? I could screw open the lock and put the motherboard inside of it? Is there a size for it or do I have to make a custom size?

[@adafruit]

Yep, go for it!

[@debayandas7123]

Can it be used with other microcontrollers, like the TIVA C series?

[@hedgehogtitan]

It is possible to get a list of all the components used for the LCD section? Perhaps even the code used? I'm not very tech savy when it comes to these kind of things

[@SandroMiccoli]

Each fingerprint ID is 512 bytes long?
Can I generate the ID without saving it to the flash memory?
Thanks and congrats for the great work!

[@Matheus-wr1ez]

nice video

[@nickschreiber6975]

Is it possible to just save and write new Images in this Fingerprintsensor, without connecting to PC? Just using Arduino and some Keys? So you can Login say Number 100 and delete it or you can login and say new finger? Is it possible or is the header from adafruit not enough to do this with the Arduino directly? Is there any possibility?

[@easyelectronics4364]

Awesome!!! When i will be able to do this stuff😘😋

[@DaiShuryoTechnus]

The prints stored stay on the boards memory only? Making sure due to security concerns.

[@premprakash8847]

love you....thank you so much!!!

[@kokeskokeskokes]

Nice gun accessory, too bad it isn't little smaller, but hey, it obviously works. Now for some mechanics.

[@garyhilson7220]

Just wondering, are you a engineering or programming student? You got some good ideas!

[@rismaco]

according to the coding, will i able to assign different work to different fingerprint?

[@orirnda]

keepvid .com you can copy any youtube url and download it as a video or even mp3.

[@akky487]

Thank you so much this video are very helpful for me thanksssssssssssss

[@TotterTrack]

bro can you please tell me from where i can download my code for fingerprint

[@rabbitdrink]

After registering, can you hook this up to a breadboard or some sort of analog circuit? Do you have to use an arduino with this?

[@David-to8eg]

- up to 162 finger prints can be stored in the onboard FLASH memory.
Is there a way to extend this 162 or save it in database?

[@617joshi]

I have a question, this project only works with that type of fingerprint sensor? or also it could work with another one? because I have a fingerprint sensor but I'm not sure if it can be adapted to my arduino. Thanks and nice tutorial.

[@julianopen]

you have to research about your fingerprint sensor and how it works and then you will see

[@chaitanyayechuri]

My finger print sensor light is not glowing contnously. Is it that the finger print light sensor should glow continously. Or if the blinking is because serial transmission

[@SlavVjache]

hi. can you add in library function : WriteNotepad , ReadNotepad ?

[@thespicehoarder]

would it be possible to hook this system up to the inside of my computer, where I can then use it to unlock and log in?
P.S.
I do not want to use USB (they are too messy)
But I'm open to using Bluetooth or wireless, as my system supports it.

[@electromachine3072]

can it possible to build keypad lock system and fingerprint locking system in one mocrochip

[@normanpanashe6649]

how do you connect this fingerprint to an esp3 module

[@suhijo]

What if I want to store the fingerprints on a computer? I want to verify over LAN?

[@mw2isepic1]

Thats amazing

[@22dab95]

My digital output pins only make my LEDs very dim. I can't get them as bright as the ones in the video, even with no resistor. Am I missing something?

[@hemantraturi3582]

Is your library file compatible with all kind of FP sensors or is it specific to yours???

[@Infkkkkk]

hey, can i make history/logs.txt?
i would like to make it works with web.
thanks

[@AronIIStone]

Hello, I tryed use SFG DEmo, but I get also one answer "open device fail. Please check the password and the device address!".
I'm shure, that I connect all pins true, but he didn't want work.
PS: when I touch button "Open Device" and enter number of com-port of this device, Arduino UNO start lighting on L-led, and then turn on always

[@timothyfiliault1972]

[@lestertrinidad1180]

Is it possible for the green light to stay switched until I scan my finger print again for turning off?

[@reecelytle8589]

Could this be used to power on something if the finger print is positive?

[@GrandmaSkillz]

Hi Adafruit! I am interested in a project using this fingerprint sensor and arduino board. Could you please tell me what language this code is in?
Thanks,

[@TheDemopan3]

Hey,
The Arduino IDE uses a modified form of C
Hope this helps!

tq .

[@yhruiho]

if i want i can overwrite the program of this finger print scanner module?

[@bilelameur9803]

so as it is shown that if the fingerprint is correct then it shows you the finger id#. i want to add an error message if the finger print is wrong or it isnt stored in the sensor, what should i do??

[@denny.007]

I have question, after we enroll the finger to fingerprint module, and then the power is shutting off, is the finger still stored? pls answer me, thx b4

[@julianopen]

yes it remains stored

[@shakirullah4936]

sory one other question remind,, optical F.P device can store 80 fingerprint templates but can't more, so i am confused about this that than how we use it in elections..? is it can support other flash or any data base..?

[@ricarleite]

OK, so, what if I plug off my Arduino? Where does it save the IDs? At the EEPROM?

[@xeroanonymous93]

can I increase the storage capacity of templates from 162 templates to maybe say 20,000 templates using an SD card or say an external HDD?

[@ShariqAyazTech]

+Taki Uddin Assalam-O-ALukum,
have you got the solution by using the same sensor? i have same query or can it save into computer?

[@xeroanonymous93]

+Shariq Ayaz no I haven't.. but I think you can use a SD card and SD shield to store them

[@hamzasajid3773]

can we attache green and white wire to the analog pins?

[@nickvanacker5346]

Yes you can
Just put 255 or 0

good evening.
how could i get a code of the sensor ?
put a finger and don't save the fingerprint. otherwise get a bin or hex number that refer to the finger?
can you help ?

[@omkareshwartripathi2724]

how to slove this error "Did not find fingerprint sensor :("
it displays on serial monitor.

[@Karpoev]

learn.adafruit.com/adafruit-optical-fingerprint-sensor/wiring-for-use-with-arduino
and maybe you mistake RXTX wires
I add delay and win its problem
Serial.begin(9600);
delay(2000);
Serial.println("fingertest");
// set the data rate for the sensor serial port
finger.begin(57600);

I want to automatic create id in there. Please help me. Thank you Adafruit Industries.

[@cmasterisk7818]

I have my own fingerprint scanner and i tried it on your library. The Serial monitor says that "Did not find fingerprint sensor :( ". Does that mean that your library works only on your fingerprint scanner? or i just have to make an adjustment to the codes? please help me out. thanks

Hello, I have the same problem now. Did you solve it?

[@pnkdel1]

I am also facing same problem please let me how did you solve it.

[@ishtandon2287]

i am also facing the same proublm....anyone who have solved plz help

Try both: Windows 8 and Windows 7. Plus, Try Arduino IDE 1.5.0 (or the one which does not suppot YUN). And make sure that you made all connections properly, and tight.

[@KhairulImam10100]

hey, i dont really know about arduino thing. my question, can I use the fingerprint sensor and the software on raspberry pi?

[@InfiniteQuest86]

Not sure if you figured this out. You'd be able to use a lot of the same code for talking to it. On the pi you'd connect to the serial RX/TX GPIOs and use serial communication that way (rather than the Arduino serial 2 and 3 pins). Depending on pi version you'd need to open and talk through /dev/ttyAMA0 or whatever the serial device is.
