This small laser transmitter module works on 5V. The laser outputs a beam of 650nm (red) of approximately 5mW. Connect this module to a motor as an interactive laser pointer. By moving the laser quickly, it is also possible to make a simple projection.

NB: The signals on the module may be incorrectly indicated, if the module does not work properly, connect [S] to GND and the [-] to +5VDC.

KY-008 Arduino code

The following Arduino sketch is a laser blinker. It will continually turn the laser on and off in one second intervals.

int laserPin = 13;

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

void loop() {
	digitalWrite(laserPin, HIGH); // Turn on the laser head
	delay(1000); // wait for one second
	digitalWrite(laserPin, LOW); // Turn off the laser head
