Capacitive Fingerprint Sensor Arduino Tutorial || R502/R503 Fast & Best Fingerprint Scanner

[@iHayri1]

Magnificent , I had this sensor for a long time and tried several codes and libraries and none of them worked, you Sir, made it work, thank you so much. I was about to throw it away as I thought I killed it with 5V serial connection but it does work, just connect the red wire to the 3.3V output of the Arduino UNO and the green and white wires to pin D2 and D3, mine were reversed btw. Now I can make a custom board and use this little marvel. Thank you so much 🙂

Its very nice to know that finally you made it work.

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

[@RoyceGerikChua]

Is there a possibility to copy fingerprint data ober to a 2nd r503 scanner?

[@unknownman5498]

sir can i store fingerprints in any server ? so that i can access that data from any of the connected module ? and can i store more than 200 fingerprints if it is stored anywhere else?

[@shubhamshah4739]

Sir is there any module available for virtual implementation in proteus ?

[@mozartheart2958]

Great video, thanks! Q: Adafruit library is meant for optical fingerprint sensor I assume, and this is a capacitive Fingerprint Sensor. Does not capacitive fingerprint sensors use a different algorithm than optical?

Why are there two separate power wires for the device and the touch sensor? (red and white wires)

[@muhammadadreesghaffar2322]

What is the code for led blink in r503 ???

[@armansaif8447]

Awesome video and great explanation sir 🔥

Hey, I bout the SFM-V1.7 capacitive fingerprint sensor, but I don't seem to find any documentations on it, like it's arduino codes, can you help please?

[@1894ahmad1]

Thanks for your great video, but mine didn't work at all. Sensor isn't recognized while I did everything as explained in the video.
Anyone else having same issue? I use R503 sensor.

Can I have a product to display company logo on screen when I puth my fingerprint ?

[@aanchalnarsinghani7854]

Hello sirr...can you please share the link of fingerprint sensor R502/R503

[@electronicsworkshop7131]

Great explanation

[@robin7119]

How did you connect the Red and White wire into 1 wire?

Breadboard

[@korbiniankoch]

Is the fingerprint stored on the sensor chip or the Arduino?

[@Oscat-si4tp]

sensor chip
