 // Pin 13 has an LED connected on most Arduino boards.
 // give it a name:
 int led = 13;
 
 // the setup routine runs once when you press reset:
-void setup() {                
+void setup() {
   // initialize the digital pin as an output.
-  pinMode(led, OUTPUT);     
+  pinMode(led, OUTPUT);
 }
 
 // the loop routine runs over and over again forever:
 void loop() {
   digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
-  delay(1000);               // wait for a second
+  delay(4000);               // wait for a second
   digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
   delay(2000);               // wait for a second
