**broken link removed**
the above link is a project im about to begin just for the fun of it, not intended for security purposes. I have all of the parts except for the IC's which i havent bought, havent found many. Could there be any replacements for these two, as in a part that combines both or just simply on that can adequately replace these? I am not looking for project involving programing chips, (does this circuit have to be programmed with a programmer???). Also, what type of keypad must be used for this, will any pretty much do as long as it has 9 keys?
any help will be greatly appreciated.
regards,
ivan
