This project is based on a previous one I published, where I took an old safe and replaced its control board with an ESP8266 D1 Mini to make it into a modern OTP safe.
This time, I’m adding a Fingerprint sensor to allow for a second method to unlock the safe, including a way to enroll new fingerprints.
The plan is to have the fingerprint sensor work in parallel to the keypad, meaning that one can open the safe using the keypad’s OTP or using the fingerprint.
