Example Code for Arduino-Fingerprint Enrollment

Hardware Preparation

• UNO x1
• Fingerprint Sensor x1
• Fingerprint Sensor Cable x1

Software Preparation

• Arduino IDE V1.6.5 Click to Download Arduino IDE
• Fingerprint Library: Click to download library files
• Arduino Library Installation Tutorial

Wiring Diagram

Other Preparation Work

• Download and install the Fingerprint Library.
• Open Fingerprint Library sample code -> fingerprint -> examples -> enroll.ino.
• Connect UNO and fingerprint module according to the connection diagram.
• If you want to clear all previous saved fingerprint template, please change the number which arrows point 0 to 1, if you don't want to clear all fingerprint data. just keep it "0" in the code.
• Select the Board and Port.
• Upload.
• Open Serial monitor.
• Set Serial baud rate 9600.
• No line ending.
• Check Autoscroll.
• Set the NL mode to the NL+CR.
• Enter your fingerprint ID in the serial monitor and then click the "Send" button.

Sample Code

• Open Fingerprint Library sample code -> fingerprint -> examples -> enroll.ino.

Result

After you finish seting its parameter and make sure the connection is right, you will get this display in the serial monitor：

Don't move finger until you get "Remove finger":

Don't move finger until you see "Remove finger":

It will tell you to enter the fingerprint again, put the same finger on the module again. Don't move finger until you see "Remove finger":
