Multi-Purpose Button Setup

[arretx]

I haven't connected any of the pads P1 - P3 on the back of the board yet because I haven't quite figured out how I should be connecting them.

If I simply want to be able to press a button on one side of the door to trip the locking mechanism, which pads would I solder together to make that happen?

Is the button shorting the RFID reader connection to simulate the exact function of scanning, or is there a separate function written to handle the button?

This is the steps to make open, push button:

1. It is possible to wire normal tactile button or big size momentary switch to a most right terminal called "BTN/IN".
2. Than, you would need to solder combination on the 3-way pads on the back of the board. P1 and P2. Solder together poles 3 and 1 on those pads.
3. Set in the firmware GPIO14 to be open lock pin
4. Once you press the button, the lock will be opened and that event will be recorded in the logs.

Practical use of that is if you want to have indoor open door switch.

Those pads can be found at the bottom of PCB.
