My Gateway/Moteino system to control an entrance gate lock is coming along nicely. I'm basically replacing an off the shelf keypad system with the Mote system.
One item remaining open is the "exit" button on the inside of the gate that people press to unlock the gate so they can exit.
Now, sure, I get it, I can put a Mote at that exit button location but I'm starting to run out of Motes!
I already have wires running there for the existing exit button...
Is there any danger in running a NO button to the Mote system to accept exit requests a longer distance? On the breadboard, it is just a simple press button into a D input using the internal pull-up resistor. Pressing to ground initiates the event. What if I were to locate that button 100 feet away for instance?? Is the extra capacitance of the wire run going to cause problems? Anyone have any experience with this?
