Plan B for HoloCube problems

[archerindigo]

Possible cases:

• Fatal problem with the PCB that we won't be able to build the HoloCube
• Part of the HoloCube is not functional:
  • Antenna not working, wireless connectivity is lost
  • MCU not working, the HMI is lost

Plan B (if the ordered PCB fails but the 2048 game is working well on dev board):

Use Wang's ESP32 board, which loaded with the 2048 game but no IMU control. Look for another possible mean of control:

• Place a mobile phone on the table which is loaded with a BLE serial application.
• Use the existing PS4 controller in the escape room.

Plan C (if HoloCube and the 2048 game cannot be used at all):

• Keep using the numpad of the safe for unlock
• Place 2 batteries in the lab. When a battery is being scanned on the reader on the electric box, 2 digits will be shown on the LCD
• Combine the 4 digit together to form a password

Finally, there are 3 versions of the HoloCube / 2048 game:

1. A joystick version with a LCD screen (Minimal working design)
2. HoloCube using a ICQUANZX T-Camera ESP32 and MPU6050 breakout (bypass the problems with the PCB)
3. HoloCube using the self-designed PCB (Require extra time to fix the problems in the circuit)
