Specifications

Refer to the Design Spec, these include:

Arduino pin allocation
Edge cases - Please add to this list!
State machine to act as a structural guide for the code

Contributing Styleguide

Please use well-named camalCase variables, for example: stateRunGame instead of: staterungame

Try and limit the use of global variables
Keep functions as short as possible and easy to read

Libraries

EEPROM

Required for saving non-volatile data on the Arduino
Reference

LiquidCrystal

Standard libary to help manage LCD states
Our panel is 4x20 pixel
Reference

Chrono

Timing library that will be primarily used for user-input timeouts
Reference

Bluetooth

Not really a library, but refer to this tutorial to implement bluetooth using a serial connection

Issues

Code filesize may be too large for the Mega
Edgecases may not be covered in production
Too much current drawn from the Mega
