Cost Summary
Possible Improvements
HARDWARE
SECO is an electronic mailbox
The mailbox will be made from a secure material
The mailbox will have a fingerprint identification lock
Key lock will be used to override fingerprint scanner lock
An infrared transmitter and receiver will be used to detect mail
SECO will have email capabilities
Project Description
Environment Indoor environment Weather elements were not a factor
Size Large enough to allow at least an 8 ½” X 11” letter
size paper to lay flat in the box Small enough to accommodate many mailboxes in a
common place Fits in the mail cubicles in Broun Hall.
Security Made from a material that will be difficult to pry open Marketing purposes mailbox will be made of Lexan

FIM5360-LV Fingerprint Scanner
FIM5360-LV Fingerprint Scanner
Does not require Universal Serial Bus (USB) connection
Has board dedicated to processing of fingerprint scans
Communicates with primary embedded controller with simple serial communications (e. g. request for authentication, registration, or deletion; successful or failed authentication indicated by single returned logic level)

IR Transistor vs. Photocell Resistor
Photocell IR sensor
Ambient light Most sensitive Some reduction
Blinking light at 60HZ Not detected Detected
The lock responds to electronic signals for matching fingerprint
This lock is a compact size
Has higher force standards
More expensive lock but benefits outweighed the cost
Rutherford 3510MS Electric Cabinet Lock
Amico 16.5mm diameter cabinet tool box quarter turn cam lock
Consist of a cam lock and key combination
Switch is pressed triggering a high signal Send a signal to unlock the electronic
mailbox lock key must be used to toggle the switch
Manual Lock Override
SOFTWARE
LabVIEW
LabVIEW is a high level graphical programming language that allows the user to code using a flow chart rather than text.
How to turn an LED on?
C program:DDRT = 0x01;// set bit 1 as outputwhile(1){
if(sw==on)PTT_PTT1 = 1; //logic high
elsePTT_PTT1 = 0; //logic low
