SEN0188_Fingerprint
This is an Arduino compatible fingerprint module. With the high speed DSP processor, it could also work with other serial device, like MSP430, 51, AVR, PIC, STM32, ARM and FPGA device. This fingerprint module could work alone without any principal computer or any PC software. It could store 1000 fingerprint. Support fingerprint entry, intelligent image processing, fingerprint comparison and fingerprint search mode. It also has a high sensitivity to both wet and dry fingerprint recognition. This module could be widely used in security field, such as license management .etc. It can also be used to replace the IC card, password, hardware switch in your application.

Sorry for the inconvenience first, we found this wiki library should be a fork of Adafruit fingerprint's one, the download link will be removed until we fix this wiki

- Download and install the Fingerprint Library:
https://github.com/adafruit/Adafruit-Fingerprint-Sensor-Library Click to download library files] Arduino Library Installation Tutorial *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
After you finish seting its parameter and make sure the connection is right, you will get this display in the serial monitor：
- Set the NL mode to the NL+CR
- Now please enter your fingerprint ID in the serial monitor and then click the "Send" button.
- 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"
- Stored successfully
- Keep going to input fingerprint if you want
- Similar to the fingerprint input, download the Exemples -> fingerprint.ino to UNO:
- Set Board and Port；
- Open Serial Monitor；
- If the fingerprint module is connect successful, it will always prompt you to press your fingers
- Press your finger on the screen and do not move, you may also be prompted to press the fingers, but the prompting message will be slower, if your fingerprints has been in the template, it will appear as shown
