I'm experiencing logical errors in my Arduino code that's controlling a stepper motor. The motor is not behaving as expected, suggesting possible peripheral issues. Issues i'm experiencing is the door switch is not triggering "opening" with the NO contact which should trigger a "strum" action. Also the relays A,B and C are set to have one strum for relay A, two for B and three for C. The door is to initially trigger s single strum. The code needs to allow us to hold down the remote button that triggers A, B or C relay for 5 or more seconds to allow the learning of that relay to the door trigger, So if B relay was held down for 5 or more seconds it should force the door trigger to now strum two times as it should have learned the ...
