Example Code

This Arduino sketch will repeatedly turn on and off the laser head every second.

int laserPin = 13;

void setup() {                
	pinMode(laserPin, OUTPUT);  // Define the digital output interface pin 13 
}

void loop() {
	digitalWrite(laserPin, HIGH); // Open the laser head
	delay(1000); // Delay one second
	digitalWrite(laserPin, LOW); // Close the laser head
	delay(1000); 
}
