At first we were searching for some fun Arduino projects on Youtube. One of the projects inspired us: it was a lock that could be unlocked by people knocking on the door. We tried to figure out how it works, and concluded that it might reply on some kind of sound sensor. Hence we decided to play around with sound the sensor as well.
We thought it might be hard to detect some beats made manually, as it might different slightly each time. As a result, I decided to use pre-recorded songs instead.
Hence the system should work like this:
When you play the chosen song, the lock recognises it and gets unlocked.
