650nm 6mm 5V Laser Diode Module – 5mW Mini Red Laser Dot Module

A laser diode (LD) is a type of diode that emits coherent light when current flows through it. It is a semiconductor device similar to an LED (Light Emitting Diode), but it produces a narrow, focused, and coherent beam of light (laser), typically in the infrared or visible spectrum, depending on the materials used in its construction. The 650nm 6mm 5V Mini Laser Dot Module is a compact red laser diode module designed for precise laser pointing, alignment systems, DIY electronics, and Arduino projects. Operates safely at 5V with 5mW output power.

How to Use:

Arduino Wiring:

VCC (Red wire): Connect to Arduino 5V pin
GND (Black wire): Connect to GND
Laser On/Off Control (Optional): Use an NPN transistor or MOSFET to control the laser using a digital pin

// Sample Arduino Code to Turn Laser ON/OFF
int laserPin = 7;
void setup() {
pinMode(laserPin, OUTPUT);
}
void loop() {
digitalWrite(laserPin, HIGH); // Turn ON laser
delay(1000);
digitalWrite(laserPin, LOW); // Turn OFF laser
delay(1000);
}
