Topic: Rotary Lock to Open Door Lock with Password - Willing to Pay (Read 314 times) previous topic - next topic



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
