Arc Welding Arduino Code

From my YouTube Video:

int ledPin = 13; // LED connected to digital pin 13

void setup()
{
pinMode(ledPin, OUTPUT);
}

void loop()
{
int i,count;
count=random(10,60);
for (i=0;i<count;i++)
{
digitalWrite(ledPin, HIGH); // set the LED on
delay(random(60));
digitalWrite(ledPin, LOW); // set the LED off
delay(random(200));
}
delay(random(800,2000)); // wait a random bit of time
}
