One of UNITEN’s Smart Campus initiatives is to implement automated access to engineering laboratories on campus.
You are required to propose and design a lab door passcode locking system using PIC18 with the following criteria:
1) The door locking mechanism will be a motorized lock.
2) The locking system should have a total of 9 passcode/security code inputs
and you are required to set a minimum of 4 input combinations as the passcode/security code.
3) The system should have options to set a new passcode and a master
passcode to reset any previous passcode.
4) In the initial state, use LEDs/Buzzer to indicate the system is in “STANDBY”
mode before the password is set.
5) Once the passcode is set, the locking mechanism will lock the door and
use 12V DC Lamp and Buzzer to indicate the system is in “LOCK” mode.
6) When the correct passcode combination is entered, the locking
mechanism will open and use LEDs/Buzzer to indicate the system is in
“OPEN” mode.
7) When an incorrect password is entered, there should be an alarm. The
number of attempts allowed and how the alarm should work is up to
your creativity.
You may use buttons/keypads for your passcode inputs and a DC motor as your motorized lock. You MUST use a relay to turn the 12V DC Lamp ON and OFF.
Design the entire layout with your proposed system using the PTK40A Training kit. You are required to utilize I/O ports, interrupt, and timers as a compulsory component of your project. Please be as creative as possible in designing your project. Please refer to the guideline for mini project report in Brighten. TWO (2) students in a group.
