XC4490 Laser Diode Module

The laser diode module brings a controllable laser to your Duinotech Main Board.

The laser can be driven directly from a Duinotech IO pin. As with all lasers, be

careful that the laser is not aimed in anyone’s eyes.

5V supply

Put 5V on this pin to turn the module on

Not connected

No need to connect anything to this pin.

GND

Ground connection

Ground connection

In the above example, S is connected to pin 13 on the Duinotech Main Board and – is

connected to GND, and the ‘Blink’ sketch is uploaded from the Arduino IDE (from

Examples/Basics under the file menu). This blinks the laser on and off.

Sample Code:

/*

Blink

Turns on an LED on for one second, then off for one second, repeatedly.

Most Arduinos have an on-board LED you can control. On the Uno and

Leonardo, it is attached to digital pin 13. If you're unsure what

pin the on-board LED is connected to on your Arduino model, check

the documentation at http://arduino.cc

This example code is in the public domain.

// the setup function runs once when you press reset or power the board

void setup() {

// initialize digital pin 13 as an output.

pinMode(13, OUTPUT);

}

// the loop function runs over and over again forever

void loop() {

digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)

delay(1000); // wait for a second

digitalWrite(13, LOW); // turn the LED off by making the voltage LOW

delay(1000); // wait for a second
