So, I have a question. For example, if I use the Keypad version of the code, the keypad only faces one way right? My problem is this, how do I get out of a room that has a door with keypad input as it can be only accessed from outside the room. Is there a way to implement some kind of 'Door Release' mechanism, like for example, a button?
Although I really like the keypad version, very nice Dust Puppy. Keep up the good work .
