EXCESS CONTROL

 

Planning:-

First of all we selected the voting machine. But its seems old circuit that’s why  we did not selected this project. then after it we selected mobile control project. In that there was lot to learn because it include micro controller circuit, DTMF technology & mobile technology. We spent three days on this project  to collect  its material. We showed this project to our HOD, but they refused this project . so we left the decision to make it. Then we selected the Electronic access control system- in this project user will enter the password, if it match with the stored password in controller then it will open the door automatically otherwise will denied.

Introduction:-

In Electronics Access control system , we will control the door using password protection. In thisd project we will control  it using microcontroller 89C051. we will use key matrix to enter data, if entered data will match with stored data in microcontrolller, then only it will allow the door to open , otherwise it will remain locked.

The main key in this project is coding  of password.we will use stepper motor to open the door , so that door will open step by step.

We will use LCD display to show the entered password.

It will also show the entered password match with stored password, if the password will match then it will show access successful, otherwise it will show denied. LCD dislay will also show clock. if entered password three times denied, then it will move the programmer in continuous loop & will not allow to entered password.

When signal match with the stored password then microcontroller will give its output to stepper motor  circuit through port3. it will give supply to stepper motor & rx pulses from microcontroller .

Then dooor will open.

 

 

 

Features :-

LCD display- entered password show on LCD

Programmable- flexible- programming can be change , so this project is flexible

Component easily available

Low cost

General use for security system

Applictaions:

1.    Security System of offices,lockers,rooms

2.    For cranes – we can make cranes with same logic

3.    For lift control- with change in programming we can change in to lift control circuit
