🔴 What Is a Laser Module?
  • A laser module is an electronic device that emits a focused beam of light (laser).
  • Common in electronics kits as a laser transmitter module.
  • Usually contains:
    • Laser diode
    • Lens (for focusing beam)
    • Driver circuit (to control current safely)
🔍 Key Features
  • Wavelength: ~650 nm (visible red laser)
  • Operating Voltage: 3 V – 5 V DC
  • Current Consumption: ~30–40 mA
  • Output Power: Typically <5 mW (safe low-power class)
  • Beam Type: Focused dot (sometimes line depending on lens)
  • Size: Small and compact (easy for embedded projects)
⚙️ Pin Configuration (Typical 3-Pin Module)
  • VCC (+): Power supply (3–5 V)
  • GND (–): Ground
  • S / Signal: Control pin (HIGH = laser ON, LOW = OFF)
(Some modules have only 2 pins → always ON when powered)
🧠 How It Works
  • Power is supplied to the laser diode.
  • The diode emits coherent light (laser beam).
  • The lens focuses the beam into a narrow, straight line or dot.
  • If a signal pin is present, a microcontroller can turn it ON/OFF or blink it.
📌 Applications
  • Laser pointer / indicator
  • Security systems (laser tripwire alarms)
  • Object detection (with LDR/photodiode receiver)
  • Alignment & positioning systems
  • Robotics and automation projects
  • Laser communication experiments
