LifeTrac Remote Control

Original control prototype that was built and wired but never tested used Arduino Wireless SD Shield with 8 channel relay and metal toggle switches.

Is it viable to use a game controller for controlling a safety critical system?

Considerations

• Wireless input configuration needs to be secure
• Microcontroller resilient to lack of input
• Redundant wireless interaction and/or controls override with Universal Controller MINI12864
• Signal https://en.wikipedia.org/wiki/Mesh_networking
• Integration of bluetooth in Arduino Mega 2560 https://www.dfrobot.com/product-1175.html (looks like the chip shortage has become ubiquitous now eh?)

Using Xbox one controller (updated firmware for BLE) with Arduino Nano 33 BLE Sense xpadneo as reference for programming bluetooth controls into microcontroller
