Hello,
I am trying to use an old rotary phone dial to communicate with an Arduino uno and trigger a lock to open a door.
Ideally, the user will input a series of digits and the arduino will trigger the lock (which is triggered just from opening and closing a circuit). I would like to embed the passcode directly into sketch if possible.
Currently able to use the rotary dial as a basic input to unlock the door, but am stuck on implementing a password.
Willing to pay up to $50 USD to get this working
Thanks!
