![]() ![]() Connect the Arduino to your computer and make sure that you are using the correct port. This will open up the code to enroll the fingerprints.ĥ. To access the code to enroll the fingerprints, go to File -> Examples -> Adafruit Fingerprint Sensor Library -> enroll. Most of the code is already included in the library. Look up the Adafruit Fingerprint Sensor Library and install it.Ĥ. Then in the Arduino IDE go to Tools -> Manage Libraries. Download the Adafruit Fingerprint Library from GitHub: Adafruit Fingerprint Sensor Library.ģ. Download the Arduino IDE (if you don't already have it installed) from this link.Ģ. Connect all the wires and components as per the circuit schematic above.ġ. Since the wires of the fingerprint sensor and solenoid lock are stranded, we recommend soldering solid wires to each stranded wire and adding heat shrink (to help with connections).Ĥ. ![]() Do the same thing for the solenoid wire: Remove the JST connector and strip the wires.ģ. Once you correctly attach the wire harness to the fingerprint sensor, remove the JST connector on the other hand and strip the wires. You can find more information about the fingerprint sensor and what each wire corresponds to by going to this link.Ģ. **Note: when referring to the diagram and comparing it to your own fingerprint sensor, make sure to hold the fingerprint sensor in the same orientation as the image! (In the image above, the fingerprint sensor is upside down). The only wires we will be using for the fingerprint sensor are the RX wire, TX wire, VCC (power) wire, and GND wire (refer to image). Make sure the orientation of the cables is correct (refer to the image above). Attach the ribbon cable to the fingerprint sensor.

On the other hand, if it's someone else trying to get through, access is not allowed and the door remains locked. If a match is found, access is granted and the door opens. The next time someone places his/her finger on the sensor, it matches the data obtained through the finger with the pre-saved values. This process is then repeated every time you want to grant someone access. Once you place your finger onto the scanner for the first time the conversion into numerical data takes place, and the fingerprint template is saved. When the technology which can recognize and differentiate between fingerprints is deployed in securing access to a doorway, you get a “Fingerprint Door Lock System”.īasically, fingerprint locks operate by scanning and converting your fingerprint data into a numerical template. This makes them very suitable as long-term markers of human identity. What is more, they are also very difficult to fake or alter and can endure over an individual’s lifespan. Human fingerprints are extremely detailed and nearly unique. However, an unforeseen consequence of this particular step in the evolutionary process was to grant humans a fantastic method of identification. The patterns were an important outcome of human evolution as they enhanced our ability to grip. Although the name in itself is pretty self-explanatory, a fingerprint door lock may be defined as “a system which grants access to authorized personnel by virtue of recognizing their unique fingerprints.” You have probably looked at your hands countless times and noticed the ridges and valley pattern. ![]()
