How to Use Tube Laser Module: Examples, Pinouts, and Specs

The Tube Laser Module by Laser (Part ID: Red Laser) is a versatile device designed to generate a focused beam of light. This module is commonly used in applications such as cutting, engraving, and other precision tasks across various industries. Its ability to produce a highly concentrated beam makes it ideal for tasks requiring high accuracy and fine detail.

1. Power Supply Connection: Connect the VCC pin to a 5V DC power supply and the GND pin to the ground of your circuit.
2. PWM Control: The PWM pin can be connected to a microcontroller (e.g., Arduino UNO) to control the intensity of the laser beam. By varying the duty cycle of the PWM signal, you can adjust the brightness of the laser.

• Safety First: Always wear appropriate eye protection when operating the laser module to prevent eye damage.
• Heat Management: Ensure proper heat dissipation to avoid overheating the module. Use heat sinks or cooling fans if necessary.
• Stable Power Supply: Use a stable and regulated power supply to prevent voltage fluctuations that could damage the module.
• Focus Adjustment: Adjust the focus of the laser beam according to your application requirements for optimal performance.

const int laserPin = 9; // PWM pin connected to the laser module

void setup() {
  pinMode(laserPin, OUTPUT); // Set the laser pin as an output
}

void loop() {
  // Gradually increase the laser intensity
  for (int i = 0; i <= 255; i++) {
    analogWrite(laserPin, i); // Write PWM value to the laser pin
    delay(10); // Wait for 10 milliseconds
  }

  // Gradually decrease the laser intensity
  for (int i = 255; i >= 0; i--) {
    analogWrite(laserPin, i); // Write PWM value to the laser pin
    delay(10); // Wait for 10 milliseconds
  }
}

1. Laser Not Turning On:

   • Solution: Check the power supply connections. Ensure that the VCC and GND pins are properly connected to a 5V DC power source.

2. Laser Beam is Weak:

   • Solution: Verify the PWM signal from the microcontroller. Ensure that the duty cycle is set correctly to achieve the desired intensity.

3. Overheating:

   • Solution: Ensure proper ventilation and cooling. Use heat sinks or cooling fans to dissipate heat effectively.

4. Focus Issues:

   • Solution: Adjust the focus ring on the laser module to achieve a sharp and precise beam.

Q1: Can I use a power supply higher than 5V?

• A1: No, using a power supply higher than 5V can damage the laser module. Always use a regulated 5V DC power supply.

Q2: Is the laser module safe for continuous operation?

• A2: Yes, the laser module is designed for continuous operation, provided that proper cooling measures are in place to prevent overheating.

Q3: Can I control the laser module with a different microcontroller?

• A3: Yes, you can control the laser module with any microcontroller that supports PWM output.

Q4: How do I clean the laser lens?

• A4: Use a soft, lint-free cloth and a small amount of lens cleaning solution to gently clean the laser lens. Avoid using abrasive materials.
