The main aim of the project is to design a secure bank locker accessing system using PIC Microcontroller. The project automatically alerts regarding unauthorized access though buzzer, if he tries to open the locker. This project makes a use of keypad to enter the password, DC motor works as a locker. The main controlling device of the whole system is a Microcontroller. Keypad, Buzzer and small DC motor is interfaced to the Microcontroller. The microcontroller is programmed in such a way that it continuously reads the input from Keypad. When the person enters the password, microcontroller will check that with the predefine stored password, both are matches microcontroller will access the bank locker through DC motor. Otherwise, it will horn a buzzer alarm for alerts. To perform the task, microcontroller is loaded with an intelligent program written in embedded ‘C’ language.  

The main objectives of the project are:

 

1. Buzzer alerts, if intruder tries to open the locker
2. Password based bank locker security system.
3. To achieve this task using PIC Microcontroller.

    The major building blocks of this project are:  

1. Regulated Power Supply
2. PIC Microcontroller.
3. Buzzer with driver.
4. Keypad
5. Reset button.
6. Crystal oscillator
7. LED indicator.

  Software’s used:  

1. PIC-C compiler for Embedded C programming.
2. PIC kit 2 programmer for dumping code into Microcontroller.
3. Express SCH for circuit designing.
