@tom here is my code :
#include<Stepper.h>
const int ForwardLimitSwitchPin = 2;
const int ReverseLimitSwitchPin = 3;
const int StepperStepPin = 4;
const int StepperDirectionPin = 5;
const int LimitSwitchActivated = LOW; // Limit switch grounds pin
const int StepperMaxRPM = 100;
Stepper stepper(200, StepperStepPin, StepperDirectionPin);
void setup() {
pinMode(ForwardLimitSwitchPin, INPUT_PULLUP);
pinMode(ReverseLimitSwitchPin, INPUT_PULLUP);
stepper.setSpeed(StepperMaxRPM);
}
void loop() {
// Step forward until the limit switch is activated
while (digitalRead(ForwardLimitSwitchPin) != LimitSwitchActivated) {
stepper.step(1);
}
// Step reverse until the limit switch is activated
while (digitalRead(ReverseLimitSwitchPin) != LimitSwitchActivated) {
stepper.step(-1);
}
}
