Fingerprint ID Safe

The Fingerprint ID Safe is a lock that works by either scanning your fingerprint, or entering a code. It uses 4 components: Keypad, Fingerprint Scanner, Servo Motor, and an Arduino.

FIRST MILESTONE

For my 3rd and Final Milestone I finished the project and have a full functioning product. I attached the servo on to the box so it can be locked. Since I couldn’t drill any holes on to my safe, I had to figure out creative ways to lock the both. I decided on have a hot glued perf board on the side of the box. With the fingerprint is scanned and the fingerprint confidence is greater than 60 the servo would turn 90 degrees. The servo had extensions and a L shaped stick so the “hook” can lock onto the perf board. This would lock and it, and unable to open. After you scan your fingerprint again, the servo would unlock.

SECOND MILESTONE

My second milestone, uses all the components that are needed except for the box. The keypad is assigned to 8 pins on the arduino and that is what assigns the password. The fingerprint sensor is attached to 2 other pins which declares the fingerprint. The servo is the locking mechanism on the project itself. It would turn the lock 180 degrees for the lock to unlock. For further modifications, I plan to use either LEDs or an LCD display to clearly show what is happening, rather show it on the serial monitor.
