Control circuit using pic 16F84

In summary, the conversation discusses how to ask questions on a forum and how to obtain a program to control a keypad. The individual asking the questions is advised to do some research on their own and is given a link to keypad information on Wikipedia. They are also encouraged to learn about keyboard scanning and using a microcontroller for this purpose.

We don't give out answers to homework/coursework problems here on the PF, lusy. We are willing to give you tutorial help, so that you can figure out the answers to your assignments yourself, however.

So here's a basic link to keypad info on wikipedia.org, with other links:

http://en.wikipedia.org/wiki/Keypad

And you should also do some reading about how keyboards are scanned, and why there are diodes in the row/column arrangement of the key switch circuits. After you do that reading, it should be pretty apparent how to use a microcontroller (uC) to do the scanning.
