One of my students is building an electronic lock that features a 4 x 3 matrix keypad, a PICAXE (of whatever type is needed) and a servo motor output.
He would like be able to allow the user to redefine the 4-digit PIN without having to edit the program code each time and download it to the PIC. Can anyone suggest the easiest/best way of doing this or point me to documentation where I might find a solution?
