Last year i ve made two door lock projects.
Fingerprint door lock using arduino ppt.
If you are using arduino mega then there is no need to use analog.
First of all connect the fingerprint sensor to the arduino uno.
Because it offers the flexibility to add more features to the system.
The default pins for serial communication on the arduino uno are pin 0 rxd and pin 1 txd of the board but we are going to use other pins for serial communication.
Introduction the main aim of finger print based security system project is develop a security lock system based on fingerprint scanning.
The project arduino fingerprint sensor lock is simply fabricated around arduino board.
This simple fingerprint door unlock project using arduino can be very useful for door security forensics crime investigation personal identification attendance system and much more.
Make sure you get a fingerprint sensor that works with the arduino through the serial communication.
The door closes automatically after a smalldelay.
In the future there could be many more applications like fingerprint based driving licences bank accounts operation and so on.
One was the keypad project and the second one was an rfid door lock project each with a 3d printed case and a servo to open the door.
4 to 8 working days from the date of purchase.
This is a fingerprint door lock with a black box integrated.
For connecting the keypad with the arduino we are using both analog and digital pins.
If it is not matched indication is given toalert the buzzer.
Applications of finger print secure logins via keyboard modules user identification at kiosks biometric door locks credit card security weapon activation theft protection 8.
Today i have a new one and probably the last door lock project on this channel.
We used analog pins since we need more that 14 digitals pins for this project.
Digital door lock using arduino circuit diagram.
Not only to ensure door security this project also make certain to assist in fields like forensics crime investigation personal identification attendance system and there is a lot more.
This system can prove very useful in housing buildings large offices universities and so on.
In this project we are using microcontroller for opening and closing lock based on finger print which is stored in microcontroller itself so that only authorized person will access the security lock.
