Arduino Music Lock Answered
Had this idea for some time and ill possibly do it when i learn more electronics stuff. But for now, i'll share the idea!
So imagine you have a secure locked door. Theres no keypad or keyhole anywhere on or near the door, but there is a microphone setup on it. The only way to open the door would be to play whatever song or series of notes that are programmed into the "lock" with a musical instrument.
Since there are several lock-based instructables here that use arduino boards, would it be possible to use one with whatever required components to make a lock that opens with music as a key?
