arduino十字路通灯设计代码

以下是一个简单的Arduino十字路通灯设计代码，可以让交通更加安全：

const int red1 = 2;
const int yellow1 = 3;
const int green1 = 4;
const int red2 = 5;
const int yellow2 = 6;
const int green2 = 7;

void setup() {
  pinMode(red1, OUTPUT);
  pinMode(yellow1, OUTPUT);
  pinMode(green1, OUTPUT);
  pinMode(red2, OUTPUT);
  pinMode(yellow2, OUTPUT);
  pinMode(green2, OUTPUT);
}

void loop() {
  digitalWrite(red1, HIGH);
  digitalWrite(green2, HIGH);
  delay(5000);
  digitalWrite(red1, LOW);
  digitalWrite(yellow1, HIGH);
  delay(2000);
  digitalWrite(yellow1, LOW);
  digitalWrite(green1, HIGH);
  delay(5000);
  digitalWrite(green1, LOW);
  digitalWrite(yellow1, HIGH);
  delay(2000);
  digitalWrite(yellow1, LOW);
  digitalWrite(red1, HIGH);
  digitalWrite(green2, LOW);
  digitalWrite(yellow2, HIGH);
  delay(2000);
  digitalWrite(yellow2, LOW);
  digitalWrite(red2, HIGH);
  digitalWrite(yellow1, HIGH);
  delay(5000);
  digitalWrite(yellow1, LOW);
  digitalWrite(red1, LOW);
  digitalWrite(green1, HIGH);
  delay(5000);
  digitalWrite(green1, LOW);
  digitalWrite(yellow1, HIGH);
  delay(2000);
  digitalWrite(yellow1, LOW);
  digitalWrite(red1, HIGH);
  digitalWrite(green2, HIGH);
  digitalWrite(yellow2, LOW);
  digitalWrite(red2, LOW);
  delay(5000);
}

以上代码为一个简单的十字路口红绿灯控制程序，其中两个红绿灯交替控制，可以根据具体需求进行修改。注意，该代码只是一个示例，实际应用中需要根据具体情况进行调整和优化。同时，需要注意安全问题，确保代码能够正确地控制交通流量，保障交通安全。
