If the fingerprint read matches one of those stored, the relay that is connected to Pin 13 of the Arduino will be activated for 3 seconds To save more than one fingerprint, the sensor allows up to 162 fingerprints, we now retype the number of the next position where we want to save it, which in this example would be position 2, we type 2 and press enter and continue again the same instructions until all the necessary footprints are recorded, always indicating a different position so that one already saved is not overwritten.įinally we load the final program that will read the fingerprints. If the fingerprint was registered correctly, it will show the message “Fingerprint DOES match!”, followed by the position where it was saved and the message “Registered!” We save the first fingerprint in position 1 and then we give it enter and follow the instructions:
#Hardware fingerprint how to find serial#
We open the Arduino Serial Monitor to start recording the tracks and follow the instructions: What is inside in R307 fingerprint sensor

Subsequently, the reading and comparison sequence can be started to verify the fingerprints of the users and thus be able to discern and execute actions based on the result. To be able to use the device, it is necessary to save the fingerprints in its database.

The device has the capacity to store up to 162 fingerprints in its internal FLASH memory. The device works with the serial protocol, so it can be used with any microcontroller (arduino etc.) or development card. The biometric fingerprint sensor is ideal to create a system capable of protecting what you require through the analysis of your fingerprint.
