Project 4 : Telegraph Controller

The Telegraph Controller is a custom controller made to play the game 2048. Its overall design was inspired by a telegraph, which sends messages via Morse code. The purpose of the controller is to encourage methodical and thoughtful decisions and planning while playing.

It works by changing a variable, each tap of the wire changes said variable by 1. Once the value is above 0 a 4 second pause begins which allows for more input if desired. Once the pause is done the final value will determine the keystroke output by the board.

During this the lights on the board change to help the user determine what is happening. The number of white lights shows the current value, while purple lights appear once the board is ready for more input. This is demonstrated in the embedded video below, however, one issue with the board is that the lights may stop displaying purple. I believe this is due to the fact the code which updates the pixels according to their value runs in parallel with the normal code and can sometimes get ahead of it. Skipping over the purple. Despite this the controller still works perfectly fine when this happens and the issue is only cosmetic.
