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.

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

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

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)?

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.

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

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 ?

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

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.

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

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?

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?

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!

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

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?

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?

how do you connect this fingerprint to an esp3 module

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?

can u make a finger print lock with motor

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

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

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!

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

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

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

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??

I have done all steps and light in fingerprint sensor is also ON but while in serial moniter it execute till ( waiting for fingerprint) and then i put my finger in sensor it not happening anything it's not scanning my fingerprint not matching and even not enrolling.....please help me

- 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?

very good and simple!!!! thanks

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

Hi Adafruit Industries. Please help me. How can I retrieve those id's save in fingerprint. To create id automatic without input id# when I enroll some finger. I plan to make id# increment. Ex: Ready to enroll a fingerprint! Please Type in the ID # you want to save this finger as... I want to automatic create id in there. Please help me. Thank you Adafruit Industries.

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

hello guys, is it possible to connect raspberry pi with fingerprint scanner model pm10a? HELP, PLEASEEEE

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

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.

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

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

hi there, i have problem with my fingerprint project, since my project connected to HMI which required modbus rtu protocol to communicate. i dnt know how to connect it..can u help me? thanks

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 ?

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

Do you need to add extra code for the rgb led display

Hello, I bought a fingerprint 751 but when I fed my Arduino board , the sensor becomes red and 1 second after it turns off and therefore it is not detectable because it is offline , you have solutions for solve my problem?

Hello, my sensor panel is not blinking red, and when I try to enroll it,goes like this: Adafruit Fingerprint sensor enrollment Found fingerprint sensor! Ready to enroll a fingerprint! Please type in the ID # (from 1 to 127) you want to save this finger as... Enrolling ID #1 Waiting for valid finger to enroll as #1 Communication error How to deal with it?

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

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

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?

how can i download this (for seminar purpose) ??

you can use any micro contoller...

will be thankful for you satisfctry answer.. waiting

hi ma'am/sir I am a student and working with my project for 2 months only, this is my first time to use fingerprint sensor and arduino, can i have a copy of your code? Thank you!

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

What do you call the lcd you attached to the arduino ? i want to have one thank you

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..?

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

If i buy scanner from different not adafruit will this coding still works ? cause I think it won't can anyone tell me how to change it

I am a python programmer can i use Python Language To Code My Arduino To use This Sensor??????

its possible to use this fingerprint scanner on motorcycle bike ? please reply thanks.

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

hello mam will you please let me know how to detect this..my fingerprint is not blinking continously it is just stoped when fingerprint is placed it is not detecting..due to this our project is under process .. and it is displaying as fingerprint sensor not connected

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, Pranav

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

can any one tell me what is the program for this thing ?? how can i make it work ? or where can i find the program to let it work ?

i am using a GT511C3 FPS and the serial com window shows an error "Did not find fingerprint sensor :( " any solution to this problem?

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

I'm new to this device. I'm trying to enroll fingers, but every time I enroll my finger, it shows this message, "Image taken Image converted Remove finger ID 1 Place same finger again Image taken Image converted Creating model for #1 Unknown error " What should I do now. :(

Good Job!

can we attach the fingerprint sensor to a switch?

can this be used as a power switch?

Mam can we make this for bike self starter ?

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

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.

how can I make adafruit fingerprint sensor detects if I already registered same fingerprint

How can I create my own scanner ??

nice video

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

Hi, does it work with Raspberry PI?

I want the same project for Roboduino. Is it possible???

How i make this project with Fingerprint sensor gt511...can u give me the code..

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

how you display a message by id.. And how i want to list all id that i has been scanned?

R305 finger print module is working with Arduino and using this code. Do not use MAX232 in interfacing.

Hi, I am trying to enroll my fingerprint but when its is asking to place again I getting UNKOWN ERROR Place the finger again and its keep asking like same. What should I do can any one suggest me

Can i use the fingerprint sensor GT-511C1R?

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

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?

hi can using this with micro controller 16f874? thanks

Could you use it with a rasberry pi to?

is it possible to extract the user ID file after enrollment??

I need a system to identify several people and I throw an identification code for each of these people. This for access control. This system allows me to do this? already have some code for this purpose? thank you very much.

Its not working in gt511C3 Showing that sensor is not found Can you help me ???

provide me any kitng buyng website for the project of electonic voting mchine

good evening ... can you send the complete code for this project. thank you. :)
