Story

have you wondered the traffic light on the road

we are programming the same

the only difference is we are representing the minutes into seconds here.

Code

Here we go with the code

int ledPinr=10;
int ledPiny=9;
int ledPing=8;


void setup() {

  pinMode(ledPinr,OUTPUT);
  pinMode(ledPiny,OUTPUT);
  pinMode(ledPing,OUTPUT);
  
  // put your setup code here, to run once:

}

void loop() {

  digitalWrite(ledPing,HIGH);
  delay(5000);
  digitalWrite(ledPing,LOW);

  digitalWrite(ledPiny,HIGH);
  delay(3000);
  digitalWrite(ledPiny,LOW);


  
  digitalWrite(ledPinr,HIGH);
  delay(5000);
  digitalWrite(ledPinr,LOW);

  // put your main code here, to run repeatedly:

}
