Upload the code to your Arduino as usual. Select the File-Examples-Adafruit_Fingerprint-fingerprint example sketch. If it is not a finger in the database, you will get a failure notice.Ĭonnect the fingerprint scanner as shown in the image below. If it is the same finger, you should get a match with the ID number. When prompted, press a finger to the sensor. On success you will get a “Success to enroll!”.Ĭlick on the Search button on the right hand side. You will then have to repeat the process, to get a second clean print. You can then see a preview of the fingerprint if you clicked the preview checkbox. The software will ask you to press the finger to the sensor. When the box comes up, enter in the Address ID you want to use. To enroll a new fingerprint click the Preview checkbox and press the Enroll button next to it (Con Enroll means continuous enroll, use it if you want to add many fingerprints). They should default to 57600 baud and security level 3 so set them if they’re wrong.

You can change the baud rate in the bottom left hand corner, as well as the security level. You should see the following screen, with a “Open Device Success!” message and some device hardware information. Select the COM port used by the Arduino and press OK when done. Start up the SFGDemo software and click Open Device from the bottom left corner. If you’re using a Leonardo, Micro, Yun, or other ATmega32U4-based controller, use this sketch instead of the blank sketch – it allows Leonardo to pass serial data between fingerprint reader and Windows.Ĭonnect to the Arduino TX, Rx, 5V and GND as shown in the picture below. This sketch will allow you to bypass the Atmega chip and connect the fingerprint sensor directly to the USB/Serial chip converter. You can do this by connecting it directly to the USB/Serial converter in the Arduino. The easiest way to enroll a new fingerprint is to use the SFGDemo software on Windows.įirst up, you’ll want to connect the sensor to the computer via a USB-serial converter. It also works with the Adafruit-Fingerprint-Sensor-Library.Įnrolling and Searching Enrolling New Users with Windows This sensor can be used with the SFGDemo software on Windows – it makes testing the module simple, you can also use the software to enroll fingerprints and see them on your computer screen. You can also enroll new fingers directly – up to 300 finger prints can be stored in the onboard FLASH memory. This module has a high powered DSP chip AS608 that does the image rendering, calculation, feature-finding and searching. Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash and search. Use an optical fingerprint sensor to add biometrics to your projects.
