Description:
Main concept behind this project is of a door-latch opening using a password entered through keypad. User can change this password anytime he/she wish using a keypad

Block Diagram:

Description:
It mainly consist of following blocks
1. Microcontroller: This is the CPU (central processing unit) of our project. We are going to use a microcontroller of 8051 family. The various functions of microcontroller are like:
I. Reading the digital input from Keypad
II. Sending this data to LCD so that the person operating this project should read the password
III. Sensing the password using keypad and to check whether it is a correct password or a wrong password and rotate the stepper motor if the password entered is a correct password.

2. LCD: We are going to use 16x2 alphanumeric Liquid Crystal Display (LCD) which means it can display alphabets along with numbers on 2 lines each containing 16 characters.

3. Keypad: User will enter the password using the keypad. Various keys of keypad are as following,
I. 0 to 9
II. Enter
III. Escape

Tags:  Door access system, Digital code lock, Keyless entry to home

Question and answers about this project:

Question: How much time will it take to reach project by courier?
Answer: Project PCB is ready, so it will take 2 days to complete the proejct. And then 2 to 3 days to courier the project.

Question: Can you provide a Relay at the output ? Can you change the output device from stepper motor to DC motor.
Answer: Yes, both options are possible. We can provide DC motor as well as a Relay as an output device.
