我试图使步进电机击中一个限位开关，然后点亮6个LED。个别这些都工作得很好，但当执行所有在同一时间只有电机的工作和LED只会 Flink 一次，当我甚至没有接触到开关。任何想法，为什么会发生这种情况？
下面是代码：

// Libaries
#include <ezButton.h>
#include <Stepper.h>

// LED PRE-Setup

int LED[6] = { 2, 5, 4, 6, 12, 13 };

int brightness = 0;
int fadeamount = 5;

// Constants
const float STEPS_PER_REV = 32;
const float GEAR_RED = 64;
const float STEPS_PER_OUT_REV = STEPS_PER_REV * GEAR_RED;
const int blinktime = 500;
int LED_2Interval = 500;
int StepsRequired;
int ledState = LOW;

// Stepper Motor Pre-Setup
Stepper steppermotor(STEPS_PER_REV, 8, 10, 9, 11);

// Switch Pre-Setup
int limitSwitchPin = 7;
// Previous Variables
unsigned long previousLED_2Millis = 0;
unsigned long currentMillis = 0;

//==========================

void setup()
{
    // put your setup code here, to run once:
    pinMode(LED[0], OUTPUT);
    pinMode(LED[1], OUTPUT);
    pinMode(LED[2], OUTPUT);
    pinMode(LED[3], OUTPUT);
    pinMode(LED[4], OUTPUT);
    pinMode(LED[5], OUTPUT);

    pinMode(ledState, OUTPUT);
    pinMode(limitSwitchPin, INPUT_PULLUP);

    Serial.begin(9600);
}
//==========================

void loop()
{
    // put your main code here, to run repeatedly:
    //clockWise();
    updateLEDS();
    switchLEDS();
}

//==========================

void clockWise()
//Turn the stepper motor to hit the limit switch
{
    StepsRequired = -STEPS_PER_OUT_REV / 2;
    steppermotor.setSpeed(1000);
    steppermotor.step(StepsRequired);
    Serial.println("clockWise");
};

void updateLEDS()
//Read the current state of the limit switch to turn the LEDS on or off.
{
    if (digitalRead(limitSwitchPin) == HIGH) {
        ledState = HIGH;
       /* analogWrite(LED, brightness);
        brightness = brightness + fadeamount; ----- Work in progress for a fade feature 
        for (int i = 0; i < 225; i++)

        -fadeamount; */
        Serial.println("LED ON");
    }
    else {
        ledState = LOW;
        Serial.println("LED OFF");
        delay(100);
    }

    if (digitalRead(limitSwitchPin) == HIGH)
        analogWrite(LED, brightness);
    brightness = brightness + fadeamount;
    for (int i = 0; i < 225; i++)
        ;
    -fadeamount;
};
void switchLEDS()
//Turns the LEDS on and off
{

    digitalWrite(LED[0], ledState);
    digitalWrite(LED[1], ledState);
    digitalWrite(LED[2], ledState);
    digitalWrite(LED[3], ledState);
    digitalWrite(LED[4], ledState);
    digitalWrite(LED[5], ledState);
};

最初，这是一个更短的代码，但我在另一篇文章中读到，如果我把它分成两个单独的函数“clockWise”和“updateLEDS”，这两个代码可以同时运行，但这并不起作用。
