KY-008 Laser Transmitter Module

The KY-008 Laser Transmitter module can be used as a laser pointer. It emits a dot shaped, red laser beam.

Compatible with Arduino, Raspberry PI, ESP32 and other popular microcontrollers.

KY-008 Specifications

This module consists of a 650nm red laser diode head, a resistor and 3 male header pins. Handle with caution, do not point the laser beam directly to the eyes.

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
	delay(1000); 
}
