標(biāo)題: 四位共陰數(shù)碼管模擬交通燈 Arduino程序
hello大家好，今天早上過馬路時(shí)等紅綠燈時(shí)，也想自己做一個(gè)玩玩，代碼如下，由于作者水平有限，以下代碼僅供參考，使用開發(fā)板為arduino uno

#define redLed A2
#define greeLed A0
#define yelloLed A1
int redDS=15;
int greenDS=15;
int yellowDS=5;
char signal;

int a = 9;
int b = 8;
int c = 7;
int d = 6;
int e = 5;
int f = 4;
int g = 3;
int dp = 2;

int d4 = 13;
int d3 = 12;
int d2 = 11;
int d1 = 10;

long n = 12030;
int x = 100;
int del = 55;
void setup()
{
Serial.begin(9600);
for(int a=2;a<=13;a++)
{
pinMode(a,OUTPUT);
}
   for(int A0=2;A0<=A2;A0++)
{
pinMode(A0,OUTPUT);
}
}
void loop()
{
  jiaotongdeng();
}

void WX(unsigned char x)//數(shù)碼管位選
{
switch(x)
{
case 1:
      digitalWrite(d1,LOW);
      digitalWrite(d2,HIGH);
      digitalWrite(d3,HIGH);
      digitalWrite(d4,HIGH);
   break;
   case 2:
      digitalWrite(d1,HIGH);
      digitalWrite(d2,LOW);
      digitalWrite(d3,HIGH);
      digitalWrite(d4,HIGH);
   break;

      digitalWrite(d1,HIGH);
      digitalWrite(d2,HIGH);
      digitalWrite(d3,LOW);
      digitalWrite(d4,HIGH);
   break;
   case 4:

      digitalWrite(d2,HIGH);
      digitalWrite(d3,HIGH);
      digitalWrite(d4,LOW);

      Serial.println(yellowDS);
   }
   }
}
  }
  digitalWrite(redLed,HIGH);
  for(int i=redDS;i>=0;i--){
for(int k=5000;k>0;k--){
display(1,i/10);
display(2, i%10);
}
  }
  digitalWrite(redLed,LOW);
  digitalWrite(yelloLed,HIGH);
  for(int i=yellowDS;i>=0;i--){
for(int k=5000;k>0;k--){
display(2,i/10);
display(3, i%10);
}
  }
  digitalWrite(yelloLed,LOW);
  digitalWrite(greeLed,HIGH);
  for(int i=greenDS;i>=0;i--){
for(int k=5000;k>0;k--){
display(3,i/10);
display(4, i%10);
}
  }
  digitalWrite(greeLed,LOW);
}最后有個(gè)不情之請(qǐng)，如果您會(huì)使用0x..十六進(jìn)制寫法改進(jìn)我的代碼，請(qǐng)發(fā)到評(píng)論區(qū)
