c - Arduino 电机速度 LED(Led 条形图代码)

Question

嘿，我 wounderd 如果有什么。我可以继续阅读以改进此代码的突击队吗？至少它现在可以工作，但需要做一些微调:)

如您所见，代码非常困惑且难以阅读。希望有人能帮忙。

提前谢谢。

int potPin = 0;
int motorPin = 11;
int potValue = 0;
int on = 0;


int L2 = 2;
int L3 = 3;
int L4 = 4;
int L5 = 5;
int L6 = 6;
int L7 = 7;
int L8 = 8;
int L9 = 9;
int L10 = 10;


int M2 = 40;
int M3 = 75;
int M4 = 100;
int M5 = 125;
int M6 = 150;
int M7 = 175;
int M8 = 200;
int M9 = 225;
int M10 = 250;

void setup()

pinMode (L2, OUTPUT);

Answer 1

简短回答:学习如何使用循环(for 和 while)和数组。

更长的一个:

这样定义 M:

int M[] = {40,75,...,250};

(将...替换为其余值)

并将 LedBar 函数更改为:

void LedBar()
{
    int potValue = analogRead(potPin) /4;
    if(on == 1)
        for (int i=0;i<=8;i++)
            if (potValue > M[i])
               digitalWrite(i+2, HIGH);
    else
        for (int i=0;i<=8;i++)
            digitalWrite(M[i+2], LOW);
}

此外，在设置中，您可以编写 pinMode (L.., OUTPUT); 行:

for (int i=2;i<=10;i++)
    pinMode (i, OUTPUT);
