Fingerprint sensor module connection with Arduino uno. Normally number of errors are encountered when interfacing fingerprint module with Arduino. I have fixed almost all the errors And this video guarantees you the 100% working of the sensor with Arduino. Enroll and fingerprint codings were demonstrated in this video. Since there is an issue with the Enroll coding, I have used the error-fixed version of enroll program in order to save new fingerprints in the fingerprint module. And the error-fixed enroll coding is uploaded in the FIRST COMMENT of the video so that you can access it and use for yourself. Overall, you will be able do two things in the fingerprint sensor after watching the video. One, Enrolling new fingerprints in the system. And the other one is, verifying the enrolled fingerprints and identifying them using the sensor again. Please comment for any clarifications or help and Subscribe my channel to stay updated with more of my video tutorials. :D

Did not find fingerprint sensor :(
Need help to rectify this error
What is the board you are using? Check out the compatible connecting pins for the specific board. For mega and leonardo the pins differ.
I m using Mega with pins 10 & 11. Sensor works fine with SFG Demo Software but doesn't works with Arduino.
check the wires. Green goes to 11 and White goes to 10. You connected correct? If switched, will not work. And in the coding inside the bracket it should be (11,10). If you put (10,11) will not work.
Hello. I have some questions. How can I show a message when the finger is not enrolled? Where do i put it in the code? I added two leds(red and green) and i want to make the red one light up when it's the wrong finger and the green one when it's verified. I got the green one down , but again I don't know which section of the code is for when the finger is not verified so that i can add the code to light the red led and show a message.
Thanks a lot for the video.
Hi what's the model of the fingerprint sensor you used? is this coding only for specific fingerprint sensor?
hey nova technologies can you tell me what are the two extra pins (pin 1 int and pin 2 reset) available in different fingerprint scanners such as R502 which are capacitive . Can you tell me the pin connection for them in arduino
hello. thank you for the video. very nice. i have a question that maybe u can help me with. i don't want to save the fimgerprints information in the fingerprint device, but send it and recieve it from a server. is this possible through serial communication?
excellent ....... each and every detail is covered in this video ....... thumbs up .... !!
Thanks bro... :) ... I went through all of the issues while I am doing my project with fingerprint sensor. That made me do this video with every possible details. Stay tuned for more useful stuff... :D
💯% working thanks for the video and program ........✌️✌️✌️✌️
Great. You welcome Akshay.
Hi sir! Can you help me with my problem on Adafruit fingerprint module? It just disconnects suddenly and turns off. Is it just faulty hardware?
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.
For nano which pin i can use
Hello sir,
Can tell me how l download fingerprint libraries from internet ..?
Hello, it is possible to generate a validation with the Serial meassage?
What if when somebody Dissamble the Door Loch (sensor) and replace theFingerprint Sensor withan ordanary Ardoino wich Send the verication Meassage (#1,2,3,4 und so an Found) If a am right, it is easy to hack i oder am i wrong?
Hi , I'm using AS608 fingerprint sensor
And i keeps saying fingerprint sensor can't find
iam using fingerprint module r305 iam getting unkown error please help me
if i keep the baud rate of finger at 57600 it is saying that the fingerprint sensor not found chaged different baud rates at last 74880 worked but getting unkown error
plz...help me
Congrat! It worked perfectly on the DY50.
However, on the R502 the fingerprint enrol worked, but cannot read.
Any tips?
send me the full details with error message.
Wow!!!! Thanks friend this video has come to assist me
thanks :)
Will the sensor work if I connect it to analog pins because I want to interface keypad and lcd on my project using arduino uno
No it will not. The pins are fixed. You may need to use a Mega with more pins or use I2C module for LCD display to save some pins.
is this code work for the R307fingerprint sensor
kindly reply, can i enroll more than 1 finger
Very very informative. Thank you so much
Thanks james! Keep supporting ❤️
I am using a GT-511C3 fingerprint scanner. Will the above software and code be compatible with that device?
Actually in place of "Found fingerprint sensor" , it is showing "Did not find fingerprint sensor"
hi dude, It will not work. This code is for adafruit fingerprint scanners only. you can find an alternative code for GT-511C3 in online.
Im using R307 but the serial monitor says unknown error😥, what to do now?
is adafruit library is compatible to all brand of biometric scanner?
Thanks for the concern :D
Well, it may not. It is only for fingerprint sensors. further adafruit, and r305 fingerprint sensors work fine with this. I am not sure abt others but you can give a try yet.
Is it possible to program a mobile phone finger print scanner which generally comes at the back of the mobile using these codes
?
It requires more work.
clear explanation thanks
thank's a lot is so amazing be continued it is very helpfull
Thanks a lot sara daas... keep supporting.. :)
thanks a lot..very helpfull ^^
You are welcome khadi Dja :D
Works for me!!! I'm using an economic version named JM101.. regards
Thanks and congrats. Keep supporting! :)
Thanks! i using pin 2 & 3, but in arduino leonardo, so change to 8 & 9, and work!
great. thnx. :D
I am using esp8266. what is pin on this?
Hi sir!!,
Is this video only based on Adafruit optical finger print sensor?
Hi, yes man. It is exclusive for adafruit fingerprint sensor only since that is most common for arduino. :D
Thanks man..,
give a try with r305(?) fingerprint sensor. some say it works.
Can any fingerprint sensor use the same coding or the Coding is specific used by specific sensor?
I think we cannot. It is for the specific sensor.
thannnnnnnnnnk you my friend , you saved my life . i thought that my sensor isn't working !!.
You welcome dude..! Thanks :D
did not find fingerprint sensor,,,,,,so please help
Hy, i have an error message like this "did not found finger print bla bla ", i have to try sfg demo software it work very well, but when i try example code from adafruit it shown the "did not found finger print bla". Thanks.
did you find answer for that error?
Hello sir goodmorning, i want to use fingerprint in my coin bank can you help me how? How will i know and how will i register my thumb.
im getting a communication error after i put my finger on fingerprint test please answer thanks
Thanks for your videos!
I have a doubt. Is ti possible to do the following? :
Device detects Id #1 fingerprint. And load an url somesite . com/id=1
Php server gets that id and compares if it exists. If true or not, it returns a value to the browser.
Arduino reads that value and and depending on trie or false it turns om a led ( or it can be a lock. Just an example).
Thank you!!
hi thanks.
Yes that's possible.
But i dnt know how to do that yet. I mean I never worked in php.
Nova Technologies thanks a lot for your reply!
I said php just for saying any web language. But if you say its possible its great news! One more question. I read that limit of fingerprints refistered is 300. Can i do something to increase thst number or make the sensor uses computer's memory?
Hi,
The sensors normally have 500 or 1000 templates memory.
If you want to send the fingerprint images to computer, you can do. But you will need some additional software and configuration. Then you can save any number of fingerprints.
Hey i found some compilation error for board arduino/genuino uno and code doesn't working.. Please help
send me the error details via mail
For finger print sensor r307?
thank you soooooooo much sir
You are welcome
I follow all the things shown in the video , and everything was ok but when I use enroll program and upload it after placing my finger it gives me a "unknown error" in the serial monitor
plz help.
I think either there is something wrong with your coding or the method of enrolling. Did you use the same coding I have provided in the comment? If you get the error still, please drop me a mail with the details so that I can check and try to help you. find my mail address here : nik261190@gmail.com
Nova Technologies thank you nova technology I come to know about the problem
tried and sloved
nice video
got very much helo
could you please show me how to bypass the mentioned problem?
hey im also getting the same problem plzzz help me out of this
i have faced the same problem.u just need to change the ide version to 1.6.5.then
it will work for sure...thumbs up to the video
Hello, I've a question, if the serial monitor stated "Did not find fingerprint sensor" what/where the possible problem?
Hi most probably the communication problem. Check the wire connections are good (you can do a continuity check). And then also make sure you are following all the steps I mentioned in the video...
hi mate, I'm still getting the "did not find fingerprint sensor :(" error in the serial monitor, i reckon its got something to do with a password. i know what the password is I'm just not sure where i insert it into the code? any help would be greatly appreciated. yours sincerely, the arduino noob.
i use fpm10a, but did not find fingerprint sensor.. i use arduino mega2560.. can you help me
I don't know anything about fpm10a... what's that?
the second part of coding is not available anymore as new verssion of ardiuno ide does not have any examples for fingerprint sensors
please someone help
more details pls
Lakin sir when give power and ground r305 fingerprint module then chip is very hot this mean module is damaged.
There may be reasons. may be damaged. or if you have inverted the power pins also, it happens. Better check with another module as well.
bro, i tried to write 1 , 2 , 3 etc. but i couldn't be written in the serial monitor....and whwn i going to type ' # ' only in the serial monitor then the enrolling start wit 0's...please help me to correct my code ...
im having an issue where the fingerprint sensor keeps asking for my fingerprint non-stop and im not sure how to fix it
if anyone has an answer to this please leave a comment
Hii sir can you help me how to fix in fingerprint system in the syatem but off for use switch how to cannect for the switch on and of system
can you explain more clearly?
Hie sir i am using r307 sensor and Arduino mega since i made the changes in the code but i am not getting anything in the serial monitor please can u suggest me what is the issue
it's showing did not find fingerprint sensor
Sir ,I need a program using this Arduino sensor
bravo great job but can you let us know where exactly in code you made the change?for better understanding
Check whether the code is available in the description box.
Can we use to another aspect so pls give us Thier code also
Please tell the header file of adafruit fingerprint urgent required
Finger print did not fund showing after enrolled plz help
thankss brother..... such a nice video.....(Y)
u r welcome dude
Adafruit_Fingerprint finger = Adafruit_Fingerprint(&mySerial);
can i know what it will do?
I will check out and mail u.
Hi, I have the uart fingerprint reader of "waveshare" but I do not recognize the arduino sketch, please help me
Well, Do inbox me your problem via my mail. I will see whether I can solve it.
HELLO SIR, may i pease know the Which FingerPrint Sensor u hav used????? .................. waiting for u reply, it will help a lot !!
It is adafruit fingerprint sensor module.
May you please assist me with interfacing two fingerprint sensors(enrolling and authentication) with arduino, i can only have one working but not two working at the same time and alos enrooling also works with one sensor when powered and i get communication error on the other sensor.
thank you
There are some other serial software pins. you can use them.
@@NovaTechnologies is used the following pins for the two sensors
SoftwareSerial mySerial(2, 3);
Adafruit_Fingerprint finger = Adafruit_Fingerprint(&mySerial);
SoftwareSerial exitboom(6, 7);
Adafruit_Fingerprint exitfinger = Adafruit_Fingerprint(&exitboom);
but the sensors interfere with each other for some reason
sir can you give me code in which if the fingerprint is correct the servo motor is driven and when finger placed again the motor gets driven the other way.
Please check my another video in the channel, the topic of the video is "How to make a fingerprint verification device at home? ". The code is available in the comment of the video. You can modify the code by adding servo moving command inside the if loop where I have now added the LED blink code.
Thanks brother
hi, I will do this project and it includes gsm shield for sending the SMS. so I want ur help bcz i am not familiar with Arduino. so how to contact you. pls qck rly
find my mail in the "about" section
UNO identifies the R307 sensor when you plug red wire to 5v, white to ground, yellow to 2, green to 3.
WARNING: Spurious .github folder in 'Adafruit Fingerprint Sensor Library' library
and did not find fingerprint test
can you help me please
but sir i am also using r305 will it work?
I am not sure. But people say it works.
can i enroll more than 1 finger
Yes for sure. up to 500 - 1000 fingers you can.
how can i modify the code for identifying
an invalid finger
Let me dig a little on that.
still i am not process it but after watching video like and subscribe your channel bro bcz you deserve it , done good job. i have 1 question r305 sensor, EUC interface board and relay is simple setup without coding or programing, or its also need coding or programing?
Hi Thanks bro. Yes of course. with r305 sensor also you need to program.
how can we display it in lcd?
Connect an lcd display.
Add the library
Define the connection pins
Write lcd print instead of serial print.
You can find numerous sources to connect lcd display. :D
How can I connect it to database and make website as attendance system
can. you need a software engineer.
does anyone know how one can just turn on the LCD Display using the fingerprint sensor and the Arduino UNO
Yea, simply change serial print instruction to lcd.print instructions with change in setup, global variables and adding Lcd library header file
Can I use different fingerprint modules
Depends.. some work.. some may not.

Sir plz give the prgrm for GT511C3
i am using arduino uno when upload "enroll" code the sensor is not detecting by the arduino.but it is ok with the code "fingerprint" .....
Check out the enroll coding. The pin configuration. You can find the coding in one of my videos related to fingerprint sensor.
i am using GT-511C11 fingerprint scanner and I've follow all your instructions but when it comes to fingertest "Did not find fingerprint sensor :("...I need some help...
hopefully this code might not work for that version scanners. It is best for adafruit.
Very nice video thanks what code for led on by right finger print
You are welcome. all same code. you can use any finger.
with the latest current arduino software, this code, as well as official code, are not functional. But with the old version 1.0.6, it works perfectly.
Only one bug (misbehaviour), I encounter consists in the obligation to finish the ID by a non numeric letter. for instance, to enter an ID equal to 22, I have to enter something like that : 22a or 22b, etc.
Something wrong with the arduino IDE or the serial port. TRy install another version
can i use nano tel me pin
Sir after giving all connections it's comming like finger print is not detected what's is the problem in that sir please tell me.....
Hello sir. How can I make my fingerprint ID #1/2/3 give an output to my arduino board? Like when I place my fingerprint ID #1, pin 5 on my arduino board activates a led. Thanks for your help in advance. It's for a project.
Hello, All you have to do is writing an if loop function regarding the fingerprint id. I have uploaded a video for the exact purpose of yours. You can find it in my videos with the title, "How to Make a Fingerprint Verification Device at home | Arduino DIY ". You can find the coding in the FIRST COMMENT of the above mentioned video. The answer for your question is there. Good luck.
Thanks for the help 😉
:D
Hello there the video is great. The problem I'm having is UNKNOWN ERROR, I've checked numerous times and code is correct and your procedure was followed also. Im using a MacBook Pro and software is 1.8.1 ide. I'm wondering could you help me solve this problem???
:) Hey thanks, let me see what I can do. So when do you get the "UNKNOWN ERROR"? during the verification? What is the arduino board you are using? are the connecting pins correct according to the arduino board type?
i am also getting the same problem and m using arduino nano
I solved the "unknown error" problem.
the thing is our arduino ide were not recognizing the adafruit master library simply copy paste the files in libraries folder also add from sketch menu
and most important uninstall the existing ide software and install it again
after doing all this mine problem solved now everything is working perfect
m so happy
Im using an Arduino Uno. All pin correct. Im getting the UNKNOWN ERROR during enrolling stage.
this didn't work for me...?
I have 6 coloured wires from fingerprint sensor,what can I do the remaining two wires??
Please go through all comments and replies.
do wire gundalke rakh
Thank u sir
How can I store the fingerprint data to the database? And later I want to authenticate a person from that database. Is it possible?
Well If you want to store the finger print images on the database, yes possible! but you can't do it with this sensor. There are sensors that can send the fingerprint image to the computer so that you can process further.
@@freakedtamil7120 Do you know any name of sensor that would do it?
Can I change the pins? I'm use arduino mega but I can't use these pins
You should change the pins. check out my latest video on fingerprint sensor, you will get it.
I found it, thanks. I'm going to use the 50, 51 pins
Good Luck :D
nice work

i have same problem
Is the fingerprint scanner R305 or R307?
Yes pls reply
Hi..I m using Uno with pins 2 & 3. but fingertest
Did not find fingerprint sensor :(
Need help.
Sir..
Apki problem fix hui ya ni?
Hello sir, i am trying to interface r305 fingerprint module with Nodemcu-12E module ... when i try with the enroll code of adafruit library i am getting error as "Did not find fingerprint sensor" ...can u please help me how to resolve this.....thank you
you have to change the wire connections. There is a guy who had such a problem with r307 and he solved it. He even explained how he did it. Please go through all the comments and replies. You can find his answer somewhere there.

can you please tell me that r305 will work with Nodemcu-12E
module? i have tried with different GPIO pins of Nodemcu module but i am getting the same error.
it should work. find out the "software serial pins"
i have connected the sensor RX pin to TX pin(pin 1) of Nodemcu module...and sensor TX pin to RX(pin 3) pin of nodemcu module and Software serial pins as.....
SoftwareSerial mySerial(3,1);
can you please help why it is not recognizing my r305 fingerprint module..
wires order for my fingerprint is as it follows:
red, black, yellow, green, blue, white
I connected them as you did in the video but my fingerprint sensor doesn't power on. It just flashes blue light than it stops
when i upload the code in arduino ide, i get this error:
fingertest
Did not find fingerprint sensor :(
what is the arduino you are using? uno or mega or what?
this message i have it
Adafruit finger detect test
Did not find fingerprint sensor :(
check the wiring.
@@NovaTechnologies hello sir. I also have the same problem. I already check the wirings but it says it did not find the fingerprint sensor
@@realinoperaltajr.9703 Hi You gotta change the wire connection according to the sensor type.
@@NovaTechnologies What sensor type sir ? I have Arduino Uno r3

very good video sir but
i am fracing this error in serial monitor
fingertest
Did not find fingerprint sensor :(
how to fix this
Thanks. Let's see how your problem can be fixed.
i am facing the same problem sir...what should i do??
There may be many reasons. why don't u mail me the details. my mail address can be found in the about section.
Hi, can u please tell me how did u fixed this error?
Our r305 fingerprint module is not working properly. How can correct.
Please follow the steps on the video. As the responses of the people who have commented, r305 will work in this way. Let me know what happens.
how many fingerprint can be stored?
It depends. Some module can more than 500. and some are up to 1000 fingerprints. You can find it in the specifications of the sensor from buyer.
Can u make a video that how to attach library with arduino
hi u can check in the arduino IDE settings where is your arduino folder, in that folder if you don't have a folder called libraries u can create it and copy the new libray in it amd the next time u start the arduino IDE you should have new examples from the new library
