// the setup routine runs once when you press reset:
void setup() {
  
  for(int i=5; i<8; i++)
  pinMode(i, OUTPUT); 
  Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop() {
 for(int i=5; i<9; i++){
   digitalWrite(i,HIGH);
   Serial.println("pin "+ String(i) + " : Turned  on");
   digitalWrite(i-1,LOW);
   Serial.println("pin " + String(i-1) + " : Turned  off");
