Step 2 Enter the Code

Enter this code:

// LED Fire Effect

int ledPin1 = 10;
int ledPin2 = 9;
int ledPin3 = 11;

void setup()
{
pinMode(ledPin1, OUTPUT);
pinMode(ledPin2, OUTPUT);
pinMode(ledPin3, OUTPUT);
}

void loop() {
analogWrite(ledPin1, random(120)+135);
analogWrite(ledPin2, random(120)+135);
analogWrite(ledPin3, random(120)+135);
delay(random(100));
}
