-snip-You should be able to load this with the demo.
So if I click 1 on the door numberpad it colors 1 on the other numperpad? So I could see who is trying to open the door?
You put the code in on the right side. The first row of numbers = the first digit. Second row = second digit.The code in the screenshot would therefore be 425.You would then push "425" in on the left keypad.(If I understand correctly.)
May I impose on you an idea? Why don't you instead of having a wall of prints, have it so it has only 6 print bricks, 3 of them to change the # and 3 of them to the side of it to set the combo lock.
