Button Question: Can I replace the button with something larger and if so, do you have any recommendations?
Last Programming: I want to program the wires at the top to make it so all 4 wires need to be a closed circuit, vs open. Can this be done? I know you said in description that it’s now easily able to be programmed but ust not sure how.
Yes, the code could be modified to detect when the wires are connected to ground instead of disconnected. If you are experienced with programming, I can give some details, but if not, then I’d recommend the Custom Programming item in our store, and I’d code/test that for you after getting your exact requirements. You would need a USB to serial adapter to use the Arduino IDE to upload the new code. Experience with that?
