Hello everyone,
I'm 16, I'm french and I am making a switch panel to act as a keyboard with an arduino pro micro to flight simulator on PC an XBOX. I want to use 16 switches with an off/on position connected to an CD74HC4067 and 3 rotary encoders directly to digital pins. Each switch must write a character when it is turned on, but only once. And each switch must write a character when it is turned off, but only once. About encoders, they must write a character for each step CW and each step CCW. I am a beginner and I'm bad at coding. I am trying to do a prototype with an arduino uno board that send information but not as keyboard key but as serial.print.
I wrote this code on wokwi to try and it's not working very well someone can help me pls ?
#include <light_CD74HC4067.h>
#define inputCLK 4
#define inputDT 5
#define inputCLK1 6
#define inputDT1 7
