Here's a video of it working: https://streamable.com/2jgh7
Make your own secret stash hidden as nothing more than an empty iphone box. Lock the box by sticking either of the two rfid tags over the reader (bottom left corner of the box). Unlock it by putting a specific pattern of, in my case, the blue rfid tag, wait two seconds, the white rfid tag, wait two seconds, and then the blue rfid tag again. This can be changed to any two of your own rfid tags in the code or just one instead of two.
I originally made this to be used in an escape the room I made for my friends, it worked flawlessly and it sure took them a while to figure out. Feel free to use it for whatever you like.
There are two models included, one for aligning the locking frame, and the actual locking frame itself
Materials:
- wires https://amzn.to/2x77Q1u
- arduino uno https://amzn.to/2OdlFCD
- 9 volt battery or alternative power source https://amzn.to/2Nzmqc9
- power source for arduino (a 9 volt battery, wire leading outside the box to a wall, etc.) https://amzn.to/2oYzmdO
- 1 or two rfid tags of any type https://amzn.to/2N9tKMf
- an rfid reader https://amzn.to/2oZx1iF
