Code Example

const int RedPin = 3;

const int YellowPin = 4;

const int GreenPin = 5;

//ตั้ง pins สำหรับสีแต่ละสี

 

void setup() {

  pinMode(RedPin, OUTPUT);

  pinMode(YellowPin, OUTPUT);

  pinMode(GreenPin, OUTPUT);

  // ตั้ง pins ของสีให้เป็น output

  digitalWrite(RedPin, LOW);

  digitalWrite(YellowPin, LOW);

  digitalWrite(GreenPin, LOW);

}

 

void loop() {

  digitalWrite(GreenPin, LOW);

  digitalWrite(RedPin, HIGH);

  delay(1000); //ล่าช้าไป 1 วินาที

  digitalWrite(RedPin, LOW);

  digitalWrite(YellowPin, HIGH);

  delay(1000);

  digitalWrite(YellowPin, LOW);

  digitalWrite(GreenPin, HIGH);

  delay(1000);
