In both circumstances, system will return the matching result, success or failure.Ĭonnect blue wire(RX) to pin number 10 and connect yellow (TX)wire to pin number 16. For 1:1 matching, system will compare the live finger with specific template designated in the Module for 1:N matching, or searching, system will search the whole finger library for the matching finger. When matching, user enters the finger through optical sensor and system will generate a template of the finger and compare it with templates of the finger library. The system will process the two time finger images, generate a template of the finger based on processing results and store the template. When enrolling, user needs to enter the finger two times. These two steps make the microcontroller/system to authenticate right fingerprint.įingerprint processing includes two parts: fingerprint enrollment and fingerprint matching (the matching can be 1:1 or 1:N). The fingerprint identification process has two steps that are: > Install Adafruit Fingerprint Sensor Library The following library is required for this project:ĭownload SFGdemo Software and Adafruit Fingerprint Sensor Library To read fingerprint through windows system we need special GUI software called “ SFGdemo”.Serial.println("Please type in the ID # (from 1 to 127) you want to save this finger as.
Serial.println("Ready to enroll a fingerprint!") Serial.println("Did not find fingerprint sensor :(") Serial.println("Found fingerprint sensor!") set the data rate for the sensor serial port Serial.println("\n\nAdafruit Fingerprint sensor enrollment") you need GUI software called SFGdemo or SYNOdemo download the software. Now you need to connect the fingerprint sensor module. Download the SFGDemoV2.0.rar file and unzip to a destination of your choice. While (!Serial) // For Yun/Leo/Micro/Zero/. The SFG Demo software is a simple, free program that connects your PC to the Fingerprint ID module. comment these two lines if using hardware serialĪdafruit_Fingerprint finger = Adafruit_Fingerprint(&mySerial)
pin #3 is OUT from arduino (WHITE wire) For UNO and others without hardware serial, we must use software serial. On Leonardo/Micro or others with hardware serial, use those! #0 is green wire, #1 is white (Black) GND => GND) the finger print is not light up and it starts to over heat but when l connect from left as ground, tx,rx and last vcc respectively the sensor lights up but it does not shown in the serial monitor it says did not find fingerprint sensor: It doesn't respond when connected to 5V, it only heats up
Am using fingerprint sensor r307 on my project and when l use connection from datasheet(My circuit connection is:
