Description

Specification:

5 V. Laser diode:

Operating voltage: DC 5 V.
Laser wavelength: 650nm
Diameter: 6 mm.
Power: 5 mW.
Dot: red.
Temperature range: -10 °C to + 40 °C.

Laser diod:

1. Connect directly to the DC5V power supply to work.
2. The laser head consists of three parts: a light-emitting tube core, a condenser lens and an adjustable copper sleeve. The focal length of the lens has been adjusted for you.

Code:
void setup()
{
pinMode (13, OUTPUT); // Defining pin 13 as a digital output interface
}

void loop() {
digitalWrite(13, HIGH); // Turn on the laser.
delay (1000); // Delay one second
digitalWrite(13, LOW); // Turn off the laser.
delay (1000); // Delay one second
}
