Very useful. Thanks for the video!

[@digitalartee]

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!

[@circuitdesolator]

Thanks for watching!

[@izadoradourado-nx1qy]

does it work the same with raspberry pi zero?

[@fernandotamez9384]

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

[@sirapat61]

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

[@playdragon370]

Can we do this with pi 3..pls can u tell the changes to be done

[@circuitdesolator]

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

[@kristinamcchesney8205]

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!

[@cheems08123]

hello have the same problem, have you found the solution?

[@syedazeemjaved]

sudo python and the name of your file. You do not have proper permissions.

How many fingerprint can i register?? Isnit 127? If yes, how can i expand that limit?
Thanks

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

[@JamilHussain110]

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

Red = 3.3 v

Green = Rxd
black = Grd
if you have r307 sensor
