Very useful. Thanks for the video!
May I ask if you can also connect a raspberry TFT LCD while with the finger scanner?
A very nice video thanks for the hard work.
You are a legend you saved my life from the hell🎉🎉
Great video, thank you for sharing!
Thanks for watching!
does it work the same with raspberry pi zero?
May ask why if I connect my finger scanner module to pin 5V PWR... it gives me "RuntimeError: Failed to read data from sendor"... in the data sheet of my finger scanner it says it takes from 3v to 6v
How can I make it standby on f command after finger is scanned. So I can identify next fingers immediately.
Do you know how to install the driver for the usb fingerprint reader U.are.U 4500 digital persona in linux? I tried with wine but didn't work for the driver . I'm using linux mint 21.1 or 21.2
Can we do this with pi 3..pls can u tell the changes to be done
Yes 👍🏼
@@circuitdesolator Hi. i wonder if there is a way to extract the image/template/fingerprint data from the fingerprintscanner/arduino/raspberry pi then export it as file or whatever format it can be?
finger = adafruit_fingerprint.Adafruit_Fingerprint(uart) AttributeError: module 'adafruit_fingerprint' has no attribute 'Adafruit_Fingerprint' error is coming pllease help me with this ....... im using fingerprint by ttl converter
Great video, thank you! I'm having an error while trying to run the code though. It's either "Couldn't open the port. Permission denied /dev/ttyS0" or "no such file or directory /de/ttyUSB0" depending on which code I uncomment. I wired the scanner as black-GND, white-TXD, green-RXD, red-5V. I'm also using a USB to TTL UART converter. If anyone knows what the problem is, I'd really appreciate any help or suggestions!
hello have the same problem, have you found the solution?
sudo python and the name of your file. You do not have proper permissions.
How to get a fingerprint image and save it by post request.

Thanks
How to print it ? Attendance?
how image very slow. Pls help me
Can you give more details on the problem?
@@circuitdesolator bro I'm working with r307 while running the code getting errors can you help me out from this
Thanks But I am getting an error when running the code, The error is in the Line where the finger initialized in this line..... finger = adafruit_fingerprint.Adafruit_FIngerprint(uart), sir if you help me, I will be thankful
please check your wiring.

Thanks for your reply, But I have already completed my Project...
@Jake Scerri
The problem was in my Wiring Connection...
@Jake Scerri
Red = 3.3 v
White = Txd
Green = Rxd
black = Grd
if you have r307 sensor
@@JamilHussain110 Never follow wiring using colour codes, also look for layout using the circuit diagram/spec sheet.
Im having an error pls help
Please send me the code
