I have the following design parameters and schematic below.
Design, implement and test a solution to thefollowing problem:
You will be using a PIC18F4520 microcontroller board to design and produce a versatile remotely controlled Electronic Locking System(ELS).
The laboratory aspect of the assignment is of a four,3 hour session duration.
The following tasks must be completed by the group:
Design a remotely controlled intelligent Electronic Locking/ Unlocking system that performs the following tasks:
1. The functional system implementation is based around the PIC18F4520 microcontroller. The.The stand-alone unit is remotely controlled via an Asynchronous Serial Interface by a host device.
2. The remote control aspect of the communication is via a wireless Bluetooth communication device mounted on the remote lock system while the controlling device could be a smart phone a Tab, or a remote PC. The remote device sends a three digit user selected code that locks and unlocks the system.
3. On receiving a correct 3-digit PIN the locking or unlocking function can be selected.
4. The secure code is set by the user (owner).The code should by stored in the non-volatile area of the PIC’s EEPROM.
5. The display of key entries are masked by the system from “prying eyes” by echoing the *
character.
6. The user would only be given the chance for three retry entries. An unsuccessful lock/unlock sequence will initiate an alarm condition on the remote lock unit via an on-board sounder and by flashing an RGB LED. The system should remain in active for A specified time interval
7. The RGB LED and sounder will also be used for feedback purposes during the selection of the various system operational functions.
8. The locking/unlocking mechanism of the system is implemented via a solenoid with the appropriate driver interface
