  6. Datasheets of all the components / ICs used in the project

Description in detail:

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 16×2 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

Applications and Advantages:
