Music Lock



There are a lot of locks out there. There are locks open with a key, with a combination of digits, with various bodily parts, or with a correct geolocation. I decided to make a lock that I have not seen yet. Since I am learning to play piano an idea for this project came quite naturally. I decided to make a box that would open only if a correct tune is played.
