Mastermind style safe unlock box

#Mastermind style safe unlock box
This project turns a ikea perspex display box into a lockable and unlockable display case using a Arduino MKR NB1500 board for connectivity. The idea behind the safe is to open/unlock when a user gets the right code via SMS as part of a mastermind style game.

Connectivity in this build happens via the NB1500 which is catm1/narrowband enabled but a wifi board could just as easily be used.

Both the server side code and the arduino sketch run via a MQTT broker (Mosquitto)
