hi there, i am a student i wanna know if it is possible to store the data of the enrolled fingerprints in a worksheet like in microsoft excel?
hey! great question. Fingerprint scanners like the FPM11A store the fingerprint templates in their own memory and give you an ID for each enrolled fingerprint. I haven't tried it with this scanner but I believe using the Serial.print() function would allow you to capture data and display it on the serial monitor. You could add a data logger to your project for more long term data collection. This is just my assumption....I'm going to look into it. Thanks for the question!
Can this work for a printed fingerprint scan for a game instead of an actual finger?
hey there! I like where you're going with this. I have never tried it but I don't think it would work. The FPM11A uses an optical sensor to capture a high-resolution image of the fingerprint placed on its scanning surface. It extracts detail such as ridges in the fingerprint that are stored and saved for future comparisons and you can't get that from a printed fingerprint.
Hello Sir
How do I add two LEDs to the setup and what changes do I add to the code to make the LEDs work?
Very intuitive video by the way.
Hi there! Do you want a total of 2 LEDs added to this setup? What do you want the LEDs to do? One LED can light up red for failed scan while the other light up green...etc.
Thanks for the comment! 👍
@@BMonsterLaboratory hey ik im not the og commentor but like could i maybe have that second one for future endevors?
@@emeraldmage5265 hey there! no problem. do you want the code where one LED can light up red for failed scan while the other light up green? just clarifying..
yea @@BMonsterLaboratory
I want an Arduino codes for fingerprint car engine starter and will have display. Thank you!
I like the idea! sounds like a fun project 👍
@@BMonsterLaboratory how can you help me sir?
Adafruit Fingerprint sensor enrollment
Did not find fingerprint sensor :(
WHY is ithis happen?? pls help. Are some sensors not working for this code ??
It could be a number of reasons. Wire connections, power supply, correct baud rate, update library.... What message are you getting? You're using the Adafruit library?
could be a bad sensor but you'll have to do some investigating first before you can determine that.
Are you using the same sensor as the on in the video? Did any debugging info print to the serial monitor?
Hey I am using R307 fingerprint sensor. I have connected the wire and uploaded the code properly but the serial monitor keeps displaying that "Didn't find fingerprint sensor" would you help me please? Thanks.
hey, sorry about late reply. did you get this figured out? did you try any debugging in the code ?
Hay brother, if you find any solution for it . Please let us know in the comment section. I have the same problem and I don't know how to solve it .
@@wasalyunus4553 hey there! are you having trouble running the Adafruit_fingerprint library ? If you made any changes to a library or your code is different than the code i'm using in the video, can you post it here? If it's too long you can post it to the facebook page.
I managed to solve this problem for myself. Try swapping the RX and TX on the ESP32
@@notVinodRodrigo Is this work for arduino uno??
My enrolling process is done but in fingerprint code it shows fingerprint didn't match .... What should i do?
Hi there! Try lowering the confidence. If you set it at 100, try 70.
Thank you so much 😇
@@solankiparth760 you're welcome. good luck with your projects!
Sir I don't know what's going on with my project
I have put if if condition like if finger.cofidence < 70 then it should print our confidence level finger
But now it's showing multiple I'd with same finger like for same finger sometimes show id 2 and sometime I'd 3 with confidence level of 2 or 3
Please help me
@@solankiparth760 clean the surface with alcohol, even oils from your finger can throw it off. Does your conditional check look something like this? if (finger.fingerID > 0) {
Serial.print("Found ID #"); Serial.print(finger.fingerID);
Serial.print(" with confidence of "); Serial.println(finger.confidence);
if (finger.confidence < 70) {
Serial.println("Confidence level too low!"); ? adjust the confidence 70, 80, 85...see what works best.

hi there. I can't always put code in the description or comments because sometimes it won't fit. This one is a Adafruit_Fingerprint.h library example, i was able to put it here in the comments. If you ever want it posted here or emailed to you, just ask...no problem at all. Good luck! This module is fun to play around with. 👍
