The Arduino compatible 5V laser diode module is ideal for applications such as a controllable laser pointer, theft detection, etc. It produces a small powerful beam of visible red light.

This laser diode module Arduino compatible has many interesting possible applications. It can be used with an Arduino and photoresistor to perform basic remote signaling.

WARNING: Do not point this laser at a person’s eyes. The laser is not a toy - keep away from children and people who do not understand the use of the laser characteristics. Misuse of the laser can easily lead to injury. Always wear protective goggles when using lasers; for the invisible laser, this point is particularly important. The laser must not be pointed at cars, aircraft and other transport vehicles.

Test Code

void setup () {
pinMode(13, OUTPUT); // define the digital output interface 13 feet
}

void loop () {
digitalWrite(13, HIGH); // open the laser head
delay(1000); // delay one second
digitalWrite(13, LOW); // turn off the laser head
delay(1000); // delay one second
}
