Fingerprint using Raspberry Pi

Hi All,

Today, I am going to show how we can developed the Fingerprint Scanner System that used Raspberry Pi.

The hardware that you need are:

  • Raspberry Pi 4 or less
  • Fingerprint Scanner
  • USB to serial CP2102 TTL UART Converter

Hopefully, you enjoyed it !!!

Make sure you have connected the Fingerprint scanner with USB to serial converter.

Step 1 : Install the fingerprint library

To install the library, do the following command:

sudo pip3 install adafruit-circuitpython-fingerprint

It will install at this location: /usr/local/lib/python3.7/dist-packages

Step 2 : Download the Adafruit CircuitPython script

Download the Adafruit CircuitPython script from git clone:

git clone https://github.com/adafruit/Adafruit_CircuitPython_Fingerprint.git

Step 3 : Navigate to the directory

For example:

cd Adafruit_CircuitPython_Fingerprint/examples/
