This is a puzzle that uses hardware and software to create an engaging puzzle that acts as one puzzle inside a larger escape room.
- Users unlocks a box that has an exposed color sensing chip (covered by plexi-glass) thats says "color Scan" as well as three LEDs labeled "R", "G", and "B" respectively.
- When any object that meets the requirements of red, green, or blue pigmintation, the corresponding LED will light up and a lock inside the room will open a door revealing that same color of button.
- When a red, green, and blue object has been scanned, and all buttons are exposed/unlocked, the box (images below) previously used to scan colors will begin showing a sequence of blinks from the RGB LEDS. This sequence will then be mimic-ed with button presses to input the correct "code" that was previously "blinked out" from the LEDs.
- If done correctly a new area will be unlocked, concluding this puzzle.
- Reseting the puzzle is done using a reset button that customers can use to start simon says sequence over again. Hard-reset can be used by employees to get puzzle back to state 0, using same button but with a long hold of 15 seconds. This employee reset is needed for possible isses with locks being closed, not allowing for completion of puzzle in simon says mode leading to a "jammed" state.
- Color sensing module (TCS34725).
- Arduino Nano.
- 5v Relays.
- 12v Locks.
- LEDs (Red, Green, Blue).
- Momentary push buttons.
- Code written by myself using arduino IDE, C/C++.
- Libraries:
- JC_Button.h: creates a clean (cleaner code) interaction with physical buttons, debounce functionality was biggest reason for its use.
- Wire.h and Adafruit_TCS34725.h: both used to communicate with color sensing module easier
