Hi, i'm a complete novice regarding electronics, so please bear with me.
I want to make a keypad with a display that will control an electronic lock. I'm talking about a typical 4x4 security keypad and a simple 4-digit display, but i want the keypad to act in a different way. For example, the unlocking code is 1234, but the code numbers (that will be displayed on the screen) will not correspond to the numbers on the keypad, instead they will follow different rules, for example: 1 = 8,2 pressed in succession, 2 = 6, 3 = 4,1,5 pressed in succession etc.
I would like to know how hard would be to build such a device, and a general idea of how should i go about it, as i'm pretty sure i won't be able to do this myself.
Thanks in advance.
