Note to self, make an example map
It's all about outputs and inputs which locks and unlocks certain numbers.
For example, if the code is (easy one for example) 14, then you first need to press the number one, if you press anything else you will either need to redo everything or, an alarm goes on (or whatever you like)
So, all numbers but 1 is setup so that if you press anyone of them, the alarm goes on, however, if you press 1 it will remove the output on button 4 which makes the alarm go on, and instead you add an output on button 4 which opens a door or whatever your keypad does.
and then add an output on button one which does so that if you press one - the alarm turns on.
So, it's all about turning outputs on and off, I've never done it myself but I can tell that it is quite confusing.
Only one thing I don't know about this, how are you supposed to click these small buttons?
