PERANCANGAN KUNCI PINTU RUMAH MENGGUNAKAN SIDIK JARI BERBASIS ARDUINO UNO --

ABSTRACT
With the development of current microcontroller technology, security systems can
be carried out using electronic devices as a substitute for conventional key
security systems. This door security device uses a solenoid and controls it via a
fingerprint (fingerprint). This tool is designed by utilizing the Arduino uno
microcontroller as the main controller, where the fingerprint functions as an input
device in the form of a digital image of fingerprint and gives commands to the
microcontroller to control the relay. This tool works when there is input in the
form of a digital image on the fingerprint, and if the digital image on the
fingerprint is entered correctly, the microcontroller will provide a high input on
the relay to activate the solenoid. From the results of the tests that have been
carried out, it shows that this house door lock can work well. This is evidenced by
the Arduino IDE software that the microcontroller can detect fingerprint input
properly, the delay applied to activate the solenoid will open and lock back
automatically for 5 seconds, and this design Solenoid Door Lock will work open
and lock if a 12V voltage is applied.
