Making my own Escape Room 🚪🗝️

📌 Summary:

Transformed my bedroom into an escape room! Combining electronics knowledge with programming, I designed and then put into action an experience made possible by the communication between the components and the Game Master's terminal dashboard

🖥️ Requirements:

Hardware:

• Arduino UNO
• ESP32
• LEDs
• buzzer
• lcd 16x2 display
• Shift register
• 4 Digit 7 Segment LED Display
• 4x4 matrix keypad
• Rfid reader and card
• 9v Battery

Software:

• C++
• Node-Red
• Mosquitto
• PlatformIo

🏆 Main challenges Overcomed

• Setting up and syncing the inter-device data communications (Serial and MQTT).
• Setting the room's full status control and debug log for a Game Master
• Developing the respective board's codes in a fully modulized way, making code easy to reuse in the future.

Escape Room Demonstration 🔎

The Room's first puzzle involves finding a code and inserting it in the 4x4 keypad.
The second puzzle is solved placing an RFID card on a specific book (which has a hidden RFID reader).
Afterwards, a Servo opens a box where the key to open the exit door is located.
