Problem Description
Explorer Frank wanted to turn a manual door lock into an automatic doorlock that could be opened with a person-specific code, and or controlled remotely. His reason was to be able to “check” that doors were indeed locked when they were supposed to be.
Other explorers wanted an automatic door lock so that if they pressed their emergency alert button, the emergency services would be able to get in (via the special “code”) without needing to have an external “lockbox” containing a key.
