Introduction


This is a demonstration of a two step security lock. When the lock is opened a green led will turn on for a few seconds. The green led can easily be replaced by a real door lock or something else.

First you have to type in your personal code on a keypad. When that code matches, the arduino will send a message over LoRa, after which you will recieve a message on your phone/e-mail/etc with this second code. After you entered the second code the green led will light up for a few seconds or the door/safe will be unlocked.
