Escape Room Lock Box

This instructable was created in fulfillment of the project requirement of the Makecourse at the University of South Florida (www.makecourse.com).

Access to 3D printer is required for this project.

- Arduino Uno

- Black and White PLA Filament

- 1 Green LED

- 1 Red LED

- 2x Servos (SG90)

- Wires & Jumper wires

- Small Breadboard

- Large Breadboard

- Velcro Tape

- 2x 100k Ohm Resistors

Begin by slicing each STL and 3D Printing according to your printer and slicing software. I use an Ender 3 V2 and Cura.

The schematic above is the wiring layout for the project and attached is the Arduino code. The combination to unlock the box can be changed in the int code[] line. When the code is input correctly, the servo motor will unlock allowing whatever you have in the box to fall

You want to start by assembling the box by sliding each part into the cutout grooves. Once the box is put together, you want to feed the servo motor wires through their slits to route around to the back side for connection. Using Velcro, you want to attach both breadboards and the Arduino to the back of the box. Once done, connect the wires as shown in the diagram and the project is complete!
