A thought occurred to me, so far I have only been working with one key input . This has allowed for my circuit to remain simple as there is only the need for one “sensing input”. I am worried that if I add multiple inputs without moving onto another microcontroller I will undoubtedly make the circuit far more complex.

This may drive me to consider focusing on simplified units to deploy as my first iteration. These simple versions will only have one of the following inputs: space bar, w, a, s, d, arrow keys. It will be an initial attempt to keep the cost low as I source another microcontroller to make the unit more integrated and simplified while adding more features.
