Description
This is a safe that i upgraded with latch-lock and an Arduino NANO as the brain. There are two ways to unlock the safe; 1. Via a button which takes a short press as a Dot and a long press as a Dash and the complete phrase would be a Morse code; 2. Via an NFC tag for which there is a NFR/RFID reader. The safe is battery powered which lasts about 3 months and is rechargable from the outside.
