Abstract
A keypad consists of 3 columns and 4 rows, hence the name, whenever the user taps one button, the column and the row corresponding to that button are shorted, for example, if a user chooses to tap the 5 button, col2 and row2 are shorted, if a users picks 0 button, col2 and row4 are shorted, and so on.
So how do you read a keypad using a Microcontroller?
the method used to read such input is called Scanning, you connect the rows and the columns to the microcontroller, you set the columns as outputs, rows as inputs (or vice versa) ....etc

Combination Lock with LCD and Keypad using pic16f628A:
A Brief Description:
This project is written in C language. The basic user lock is of 2 Digits.
The input is taken from a 4x3 Keypad (please see the schematic for more information) and Display the user input on a 2x16 LCD. A pin is assigned as output for activating and deactivating the lock. For demonstration I have connected an LED to that pin.
How combination lock works:
1. Turn switch on (5V DC voltage power supply)
2. A message name ....etc

A Brief Description:
This project is written in C language. Its a simple project with efficient hacking prevention from Brute Force etc. The basic user lock is of 5 Digits and Master Lock is of 10 digits so its not easy for an intruder to break the lock unless you keep the code simple.The input is taken from a 4x3 Keypad (please see the schematic for more information) and Display the user input on a 2x16 LCD. A pin is assigned as output for activating and deactivating the lock. For demonstration i have connected an LED to that pin.
