Title : Keypad 4 x 4
Introduction :
In this week, i'm continued the task at the first week and trying to combine the coding that already made before.But this week, i'm trying to use keypad 4 x 4 as a controller, and to change normal button that used last week.
What is keypad ?
A keypad is a set of buttons arranged in a block or "pad" which usually bear digits, symbols and usually a complete set of alphabetical letters. If it mostly contains numbers then it can also be called a numeric keypad. Keypads are found on many alphanumeric keyboards and on other devices such as calculators, push-button telephones, combination locks, and digital door locks, which require mainly numeric input.
So,this week i'm proceed to complete my project program/coding and the main focus is trying to program RTC (Real Time Clock ) using keypad 4 x 4 and others.

1. To solve the problem using MPLAB and Proteus software.
2. To complete program the project using Keypad 4 x 4.
Problem Encountered :
Keypad 4 x 4 is the one solution that I already choose to replace push button. Before this, I'm planning to use push button setting the date and time.But,the problem is when use the push button ,we need to up and down the button with one by one to get the digit value of date and time.At, keypad 4 x 4 already have the number or digit that easy to use and setting the date and time.

Project Description :
Keypad is a set of buttons that are connected in the matrix. Advantages of using the keypad instead of using the normal button is button keypad provides more and less I / O port. Example 4 x 4 keypad, requires 8 ports because it is connected in the matrix.We can also build their own extensions using the push button. Keypad is the input module, but programs need to set 4 as the input port and 4 port as output. Connections for keypad is shown below.
