標題: 四位共陰數碼管模擬交通燈 Arduino程序
hello大家好，今天早上過馬路時等紅綠燈時，也想自己做一個玩玩，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;
   case 3:
      digitalWrite(d1,HIGH);
      digitalWrite(d2,HIGH);
      digitalWrite(d3,LOW);
      digitalWrite(d4,HIGH);
   break;
   case 4:
      digitalWrite(d1,HIGH);
      digitalWrite(d2,HIGH);
      digitalWrite(d3,HIGH);
      digitalWrite(d4,LOW);
   break;
      default:
      digitalWrite(d1,HIGH);
      digitalWrite(d2,HIGH);
      digitalWrite(d3,HIGH);
      digitalWrite(d4,HIGH);
         break;
}
}
unsigned char number[10][8] =
{ //a b c d e f g dp
{1, 1,  1,  1,  1,  1,  0,  0},
{0, 1,  1,  0,  0,  0,  0,  0},
{1, 1,  0,  1,  1,  0,  1,  0},
{1, 1,  1,  1,  0,  0,  1,  0},
{0, 1,  1,  0,  0,  1,  1,  0},
{1, 0,  1,  1,  0,  1,  1,  0},
{1, 0,  1,  1,  1,  1,  1,  0},
{1, 1,  1,  0,  0,  0,  0,  0},
{1, 1,  1,  1,  1,  1,  1,  0},
{1, 1,  1,  0,  0,  1,  1,  0}
};
void Clear()//清屏函數
{
  digitalWrite(a,LOW);
  digitalWrite(b,LOW);
  digitalWrite(c,LOW);
  digitalWrite(d,LOW);
  digitalWrite(e,LOW);
  digitalWrite(f,LOW);
  digitalWrite(g,LOW);
  digitalWrite(dp,LOW);
}
void DX(unsigned char x)//數碼管段選
{
digitalWrite(a,number[x][0]);       //a查詢碼值表
digitalWrite(b,number[x][1]);
digitalWrite(c,number[x][2]);
digitalWrite(d,number[x][3]);
digitalWrite(e,number[x][4]);
digitalWrite(f,number[x][5]);
digitalWrite(g,number[x][6]);
digitalWrite(dp,number[x][7]);
}
void display(unsigned char y,unsigned char Number)
{
  WX(y);
  DX(Number);
  Clear();
}
void jiaotongdeng()
{
if(Serial.available()>0){
signal=Serial.read();
Serial.print(signal);
if(signal=='A'){//修改紅燈定時時間0~99s
   if(Serial.available()>0){
      redDS=Serial.read()-48;
      if(Serial.available()>0){

      int zifu=Serial.read()-48;
      redDS=redDS*10+zifu;
      Serial.print("-->");
      Serial.println(redDS);
   }
}
}
if(signal=='B'){//修改綠燈定時時間0~99s
   if(Serial.available()>0){
      greenDS=Serial.read()-48;
      Serial.println(greenDS);
      if(Serial.available()>0){

      int zifu=Serial.read()-48;
      greenDS=greenDS*10+zifu;
      Serial.println(greenDS);
   }
}
}
if(signal=='C'){//修改黃燈定時時間0~99s
   if(Serial.available()>0){
      yellowDS=Serial.read()-48;
      Serial.println(yellowDS);
      if(Serial.available()>0){

      int zifu=Serial.read()-48;
      yellowDS=yellowDS*10+zifu;
      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);
}最后有個不情之請，如果您會使用0x..十六進制寫法改進我的代碼，請發到評論區
