I forked Flip’s 4-key-keyboard to begin the second iteration.
This evening I took the dive into compiling my own .HEX files. The process of compiling allows code written in C converted into machine code allowing it to be loaded and read by the microcontroller(ATtiny85). I was able to successfully compile two different versions of the code which would allow me to have multiple inputs(keys) into the computer.
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.
